READY FOR CHANGE DEAR READER, We live in a world that is changing rapidly – politically, economically and socially. Global crises, increased tariffs, geopolitical conflicts and technological upheavals are challenging us all. But it is precisely in times like these that we see what really matters – the courage to break new ground, the willingness to take responsibility and, above all, mutual trust. binder, is not unaffected by these developments. The order situation remains volatile, but at the same time we are seeing the first positive signs on the market. Our responsibility now lies not only in allowing change to happen, but in actively shaping it. That is why we have taken important steps in recent months: the management team has been reorganised, the strategic focus on technology, efficiency and customer proximity has been sharpened, and the digital transformation has been vigorously pursued. These steps are not only intended to guide us through the current challenges, but also to make us stronger in the long term. However, none of these developments would be possible without our dedicated employees. It is they who, day after day, lay the foundations for our shared success with their commitment and expertise – they are what make binder what it is today. In this issue, we take a look at what moves us: you will get to know the new management team in our interview series, gain exciting insights into our international sales organisation and learn more about technical developments, such as in the compaction of strands. THESE STEPS ARE INTENDED TO MAKE US STRONGER IN THE LONG TERM. /02

A STRONG FOUNDATION FOR THE FUTURE A DIALOG ACROSS GENERATIONS After nearly four decades at the helm of binder, Markus Binder reflects on an impressive company history – shaped by foresight, strategic decisions, and a deep understanding of the values of a family-owned business. With the recent appointment of his son Len to the management team, this story continues into the third generation. In a joint conversation, father and son reflect on milestones, challenges, and their personal teamwork. One thing becomes clear: At binder, experience meets fresh momentum – creating a synergy that connects tradition with the future. /04
VERBINDER 63 8 WHAT ARE SOME OF THE MOST MEMORABLE HIGHLIGHTS OF YOUR TIME AT BINDER? MARKUS BINDER: Looking back over the past years, there have been many milestones, but a few stand out. One particularly significant step was the internationalization of our company. It wasn’t only the right decision economically – it also enriched our corporate culture, opened new perspectives, and strengthened cohesion across borders. I’m especially proud of the founding of binder USA. Entering the U.S. market was no easy feat. It took perseverance, trust, and a clear strategic direction before we could gain a foothold there. Today, we know it was worth it. During my time in management, I made many far-reaching decisions. Not all of them were right. For example, in 1993 we tried to enter the automotive market – in hindsight, a mistake. Probably the best decision came in 2009: to fully withdraw from that sector. It was neither easy nor quick, but it ultimately brought us stability and clarity. After 33 years at binder, I look back on this time with deep appreciation. It’s remarkable that some employees have been with us even longer – more than 40 years in some cases. That kind of loyalty is symbolic of our unique company atmosphere: built on reliability, mutual trust, and strong solidarity. This continuity cannot be taken for granted and fills me with gratitude.
HOW WOULD YOU DESCRIBE WORKING WITH YOUR SON / YOUR FATHER? MARKUS BINDER: We make decisions by consensus. It’s important to me to consciously step back and contribute my experience in an advisory way – not as someone dictating the course. I reject the patriarchal leadership style common to the post-war generation, where the senior manager continued to call the shots. That tradition has no place here. Our generation embraces a new mindset – one based on trust, dialogue, and shared responsibility. I’m particularly pleased to see that Len is setting its own course. While former managing directors at other companies often find it difficult to withdraw from operational business, we are managing the generational change deliberately and with foresight. LEN BINDER: For me, our collaboration works very well. We share a fundamental mindset and similar values. Naturally, our leadership styles differ from those of past generations. I still remember my grandfather, who had a more “old school” approach. Statements like “Now that we’ve implemented SAP, we don’t need IT staff anymore” show just how much our understanding of leadership has changed. I think my father learned from earlier patterns – keeping the positive and leaving out the negative. He has developed his own leadership style based on his experiences. What I appreciate most is the trust he places in me — a trust that’s also felt by our employees.
VERBINDER 63 10 WHAT DOES THE TERM “FAMILY BUSINESS” MEAN TO YOU— AND WHY IS IT IMPORTANT? MARKUS BINDER: To me, a family business is much more than a legal structure – it represents values like solidarity, trust and a special sense of togetherness that is rarely found in this form. LEN BINDER: My grandfather established this culture at binder, my father continued it – and I grew up with those values. They still shape how we work together today. And that’s no accident; it’s intentional. A central element of this culture is trust in our employees. We deliberately delegate responsibility and alThe family business is the glue that holds it all together. It connects generations, values, and people – and creates the space in which our culture remains alive. WHAT ROLE DOES THE BINDER DNA PLAY, AND HOW IMPORTANT ARE ITS SIX CORE VALUES FOR THE COMPANY’S DIRECTION? LEN BINDER: Since the beginning of the year, I’ve had the privilege of shaping the management of our family business alongside my father – now in the third generation. I see this responsibility not only as an honor but as an obligation: to our customers, our employees, and binder’s history. A central element that defines us – and makes us future-proof – is the binder DNA. It shows up in everything we do, from strategy to daily operations. For me, it’s an inner compass that helps guide decisions without losing sight of the bigger picture. At the heart of it all is the customer. They ensure the company’s continuity – a truth I take very seriously. That’s why we work with our customers in true partnership and as equals. Only in this way can we identify market needs early and respond with targeted, solution-oriented actions. This close cooperation creates trust, which ultimately benefits everyone. Our company culture has long been shaped by strong values. Trust, reliability, and solidarity – these are not hollow phrases, but lived practice. I was raised with these values and now experience them daily at binder – across departments, in open exchange, and in our constructive handling of mistakes. Because here, mistakes are not seen as flaws but as opportunities. Opportunities to learn, grow, and improve together. During my time working with large corporations, for example in the automotive industry, I often had the feeling that although we spoke the same language, we didn’t really understand each other. A family business simply functions in a fundamentally different way – with all the advantages that brings, but also with challenges. Anyone who becomes part of one should be aware of these special characteristics and be prepared to embrace them. As a child, I personally knew every employee. Of course, that’s no longer possible today due to our growth. Still, I try to stay in touch with as many people as I can. I make a point to not only communicate with top leadership but to remain approachable for everyone. low room for development – because we believe that people reach their full potential when they are trusted. This has been crucial, especially in times of internationalisation: we have created opportunities and handed over responsibility – and in the vast majority of cases, this has paid off. Of course, things don’t always run perfectly. But when you take people seriously, get to know them and work with them as equals, the result is usually something very positive. Personally, it’s a powerful feeling not just to be part of the company, but to help shape it. I can see that many others – especially the younger generation – feel the same. Their ideas often come directly from everyday work, where real things happen. That’s why it’s so important to listen to them, to embrace new approaches, and to simply try things out.
VERBINDER 63 12 Our direction remains clear: We aim for sustainable growth – not at any cost, but with foresight, responsibility, and a strong sense of unity that defines us as a family business. I’m deeply committed to ensuring this spirit remains tangible for all current and future members of the binder team. WHAT IS BINDER’S BIGGEST SUCCESS FACTOR? MARKUS BINDER: Without question: our employees. They are our greatest asset – and that’s not just a marketing phrase, but reality. Without them, binder wouldn’t be what it is today. They shape our day-to-day, actively contribute to our development, and embody our values. This made the recent decision regarding personnel measures all the more difficult for us. It was a drastic but necessary step to ensure the stability of the company. Believe me – this was one of the most difficult decisions I have ever had to make in the history of our company. But it’s not just one factor. It’s the mix that makes the difference: our committed employees, our high-quality products – and the foundation of an established family business that holds it all together. We’ve been successfully positioned in the market for decades, have built a solid reputation, offer a wide product range, and boast high manufacturing depth. That sets us apart. Naturally, the market has changed. Competition is much tougher than it was 10 or 15 years ago. It’s about quickly developing new products, initiating the right innovations, and bringing them to market efficiently. This is where we come in – with innovative strength and customer focus. Many of our major customers purchase several hundred different variants – from small series of a hundred units to large series of several hundred thousand units. This diversity and product range
VERBINDER 63 13 give us a clear competitive advantage, but also represent a challenge that we face every day. And one thing remains unchanged: our uncompromising commitment to quality remains at the heart of everything we do. Our brand stands for reliability, quality and solutions that really help our customers move forward. We don’t just want to satisfy them – we want to inspire them. This can only work if we work with them to develop innovative solutions that are precisely tailored to their requirements. HOW HAVE THE REQUIREMENTS FOR CIRCULAR CONNECTORS CHANGED OVER TIME – AND WHAT CHALLENGES DOES THAT POSE FOR BINDER TODAY AND IN THE FUTURE? MARKUS BINDER: From a technical perspective, we are clearly facing new challenges – both now and in the future. At binder, we are actively addressing these challenges, even if we have not yet reached our goals in some areas. The most important thing is to closely monitor the various markets. In medical technology, railway technology and now increasingly in the military sector, very specific and sometimes extremely strict standards apply. These naturally entail very different requirements, to which we must respond flexibly. All these specifications can be solved technically – that is also our strength. But there is one issue that is currently of particular concern to the entire industry: lead-free technology. Personally, I think this is a difficult path to take, especially if the changeover is not implemented worldwide. Once again, Europe is taking the lead here – but if the rest of the world does not follow suit, an imbalance will arise. This complicates many things and presents us as manufacturers with additional challenges.
VERBINDER 63 14 LEN BINDER: I’m convinced that miniaturisation and smarter connectors are major topics for the future. We have already achieved some success in this area through our innovation centre. At the end of the day, innovation is essential for our customers – especially when it is strategically established as a common thread throughout the company. Close customer contact plays a decisive role in this. Only in this way can we tors, we are also intensively involved in electronic solutions and the projects of our affiliated companies in this area. But one thing is also clear: circular connectors remain an integral part of our portfolio. At the same time, we are not only concerned with individual components, but with complete connection solutions. Cable assembly also plays an important role in this context. It not only ensures closer customer loyalty, but icant milestones in his professional life. Now, he stands at a pivotal moment – entering the company’s management – and I am confident that he will embrace this new role with responsibility, foresight, and passion. I see in him many qualities that are essential for our family business: clarity, a strong sense for people and situations – and above all: the drive to make a difference. I am firmly convinced that he has what it takes to lead binder into a successful third generation. LEN BINDER: What I especially admire about my father is his down-to-earth nature. It’s a value we’ve already talked about – and one that truly matters to me. I’m very grateful to have inherited this attitude from both my father and my mother. For me, it means meeting employees at eye level. Being approachable, accessible – and not walking through the company with a sense of superiority. I’m fully aware that, at my age, I haven’t accomplished all that much yet. That makes me all the more appreciative of the trust that is already being placed in me. That’s anything but a given – and it fills me with great pride. WHAT MESSAGE WOULD YOU LIKE TO SHARE WITH THE EMPLOYEES? MARKUS BINDER: At the moment, we’re going through a rather difficult phase together – but we are doing everything we can to turn things around. Our goal is to reconnect with the successful times of the past. I’m fully aware that the past year has been challenging for all of us. It has left its mark, including within our company. This time did not pass by unnoticed. Nonetheless, we’re now looking to the future with confidence. We’re truly optimistic about the developments ahead. also offers the customer a significantly better solution overall than a single connector alone. WHAT DO YOU ADMIRE MOST ABOUT YOUR SON / YOUR FATHER – PROFESSIONALLY AND PERSONALLY? MARKUS BINDER: Looking at Len’s journey so far fills me with pride. He has not only grown personally but has already achieved signiffind out which innovations the market really needs and what will help our customers. With our innovation and technology centre, we are very well positioned for this. Developments are taking place there that will also be important for the company in the long term. Another important area is customer-specific solutions in the field of circular connectors. It is important for our customers to develop a suitable product together, whereby the customer can rely on our contribution. In addition to circular connec-
VERBINDER 63 15 At this point, I would like to sincerely thank all our employees – for their dedication, perseverance, and trust. Without this commitment, we wouldn’t be able to look ahead with such confidence. LEN BINDER: Recently, we’ve tackled many important issues – and I believe our employees are feeling that. At least, I very much hope so. It’s important that we hold on to this sense of optimism. We are on the right path, but we still need patience and determination to get where we need to go – together. At the end of the day, I really just want to say one thing: thank you. Thank you to all the employees who have been with us for years, who identify with the company, and who support us. Don’t let yourselves get discouraged. If something isn’t working or feels tough: dig in and push forward. We’re on this journey together – with commitment and passion.
VERBINDER 63 16 WHAT PROFESSIONAL EXPERIENCES HAVE SHAPED YOU, AND HOW DID YOUR PATH LEAD TO BINDER? I have been with binder since July 2018. Prior to that, I completed a dual degree in business administration with a focus on taxation and auditing and worked for a total of ten years at the auditing firm Ebner Stolz in Stuttgart, where I passed my tax advisor exam in 2015. binder was not an unknown company to me. Through my previous job, I had been working with binder since 2009. Over the years, I developed a trusting relationship with various contacts within the company. In 2018, I finally made the move to binder, with the added bonus of already being familiar with many of the processes and teams. /05 INTERVIEW MICHAEL LANG WHICH VALUES ARE IMPORTANT TO YOU AS A LEADER, AND HOW WOULD YOU DESCRIBE YOUR LEADERSHIP PHILOSOPHY? For me, trust, respect and reliability are not just empty words, but everyday practice. They form the foundation of my leadership style. It is important to me to be open, transparent and approachable. Employees should know where they stand with me. In a company like binder with flat hierarchies, personal proximity is key, and good results can only be achieved through respectful cooperation. WHAT DOES IT MEAN TO YOU TO TAKE ON RESPONSIBILITY IN A FAMILY-OWNED BUSINESS? It is a great honour and comes with a special responsibility. In a family business, it is not short-term success that counts, but long-term thinking and value-based actions in the interests of the employees and the Binder family. Proximity and approachability are not just buzzwords here, but part of everyday life. WHAT GOALS AND CHALLENGES DO YOU SEE IN YOUR ROLE AS CFO? In the short term, the aim is to deal with the aftermath of past crises while responding flexibly to external influences. In the long term, we must continue to strengthen our business model in the financial sector in order to grow. The aim is to combine tradition and the future with the goal of ensuring sustainable growth. On 1 January 2025, Michael Lang took over as CFO, bringing vision, reliability and a clear understanding of values to binder’s financial future. His professional career took him through the world of auditing for over a decade before he made a conscious decision to move to a family business – an environment where closeness, responsibility and long-term thinking are central. In this interview, he talks about leadership values, the special features of a family business, challenges in a dynamic environment and his personal motivation to shape sustainable growth together with a strong team.
VERBINDER 63 17
VERBINDER 63 18 WHAT LESSONS HAVE YOU LEARNED FROM PAST CRISES, AND HOW DO YOU WANT TO PREPARE BINDER FOR THE FUTURE? The last few years have been marked by an unprecedented number of crises. Since 2019 in particular, the economic environment has required a new level of flexibility. It is important to maintain financial stability in order to be able to align the business model for the future. WHAT ROLE DOES THE CFO PLAY IN CORPORATE GROWTH AND INTERNATIONALIZATION? The CFO is more than just a numbers person; he is both a co-creator and an anchor of stability. In the finance department, we create the financial and organisational conditions for sustainable growth, including internationally. Our bSOs in particular require us to establish structures that enable expansion while also providing security. With all changes, it is important to give the organisation and employees time to take effect within the company. HOW IMPORTANT ARE TRUST AND TEAMWORK IN THE FINANCE DEPARTMENT? Trust is the foundation of our business, especially in the financial sector. This applies to the handling of sensitive data as well as to cooperation with the family. Figures provide insights into our activities, but behind them are people and processes. That is why teamwork is just as important here as in all other areas, because different perspectives often lead to better solutions. WHAT HAS BEEN YOUR BIGGEST LEARNING AT BINDER OVER THE PAST FEW YEARS? Change always presents an opportunity. I have learned that a strong team, mutual trust and the right attitude help us to successfully overcome even difficult times. It is crucial that we work together to shape the future. This requires the cooperation of each and every one of us. HAVE THERE BEEN DEFINING MOMENTS IN YOUR PROFESSIONAL AND PERSONAL JOURNEY? Economically difficult times were particularly formative, as they demonstrated the cohesion within the company, for example during short-time working or voluntary waiver arrangements. On a personal level, I was influenced by numerous encounters with company decision-makers and employees from a wide range of industries in both good and bad economic times. This further shaped my understanding of the need for stability, responsibility and values, and reinforced my desire to work in a family business and actively shape the future. WHAT MOTIVATES YOU PERSONALLY? I am motivated by working with colleagues to further develop our company. It gives me great satisfaction to see how cross-departmental cooperation can lead to something sustainable. In the finance department itself, the focus is on creating reliability and placing decisions on a solid foundation. This can only be achieved as a team with mutual respect, openness and a shared focus on goals. When the atmosphere is right and everyone can contribute, not only are good results achieved, but also a working environment in which people are happy to take on responsibility. WHAT ARE YOU LOOKING FORWARD TO IN THE NEAR FUTURE—PROFESSIONALLY AND PERSONALLY? Professionally, I look forward to new experiences and exciting challenges. Privately, I enjoy spending time with family and friends and look forward to mountain biking in nature to clear my head. DO YOU HAVE A PERSONAL MOTTO? A phrase that has had a lasting impact on me is: ‘Success is not about always winning, but never letting yourself get discouraged.’ It’s your inner attitude that determines how you deal with setbacks. Especially in uncertain or challenging times, it has become clear how important perseverance is. Even if the mountain seems high, every step brings you closer to your goal. WHAT WOULD YOU LIKE TO SHARE WITH YOUR COLLEAGUES? I hope to live up to the trust that has been placed in me. I see us as service providers within the company – our goal is to work together in a spirit of partnership, clarity and focus. When we all pull together, everyone benefits, and that is the basis for our shared success.

VERBINDER 63 21 /06 INTERVIEW NUNZIO TOSTO WHICH PROJECT OR EXPERIENCE HAS INFLUENCED OR INSPIRED YOU THE MOST AS SITE MANAGER OF BINDER SWISS? Without a doubt: the complete establishment of binder Swiss. After my time at my former employer Compona in 2019, I was at a crossroads regarding my professional future. I had worked as a technical administrator, later as a sales manager and member of the executive board, but I wanted to create, build something, take on real responsibility. binder gave me the unique opportunity to help shape a company from the ground up. In the first five years, we built everything ourselves: we set up storage and office spaces, established the entire IT infrastructure, and assembled a new sales team. What touched me most was the support from former colleagues – three of them joined the project immediately. A strong sign of loyalty and trust. The dynamic during that phase was incredible. There was no predefined path, only a shared goal. The fact that everything came together so smoothly left a lasting impression on me. It was a time full of energy and team spirit and certainly one of the greatest success stories of my career so far. WHICH THREE VALUES ARE CRUCIAL FOR YOU TO BE SUCCESSFUL AS A CSO? For me, honesty is the foundation of all collaboration. I believe in addressing things directly, without detours – always factually and constructively. Honesty doesn’t just mean openly expressing criticism, but also standing by your word and supporting colleagues when they show commitment. Mistakes are human and allowed. But if someone makes the same mistake repeatedly, I consider that neglectful. Reliability has accompanied me throughout every stage of my career. Especially at binder Swiss, it was critical: 18 out of 42 employees decided to join the new company out of conviction. That shows how important dependability is in working together. I place great value on clear structures and binding decisions. I only hold meetings if they lead to decisions – and what’s decided is followed through. Most important to me is consistent goal orientation. I don’t think in quarters but in long-term relationships – with both customers and my team. My focus is always on the full potential we can realize together. These three values – honesty, reliability, and goal orientation – form my foundation as CSO. As CSO, Nunzio Tosto is responsible for global sales at binder – with a clear focus on markets, people and sustainable partnerships. His professional journey has been shaped by, among other things, the establishment of binder Swiss. For him, honesty and reliability are the top priorities. These factors have a strong influence on his goals, which are in line with the challenges of international sales. In this interview, he talks about formative experiences in building a company and the strategic development of sales in response to dynamic customer needs. It becomes clear that people are always at the centre of attention – both within his own team and in relation to customers.
VERBINDER 63 22 WHAT IS ESPECIALLY IMPORTANT TO YOU WHEN WORKING WITH YOUR TEAMS? Openness, respect, and trust. I place great importance on every opinion being valued – regardless of position or experience. I encourage my teams to take on responsibility, share their ideas, and make mistakes. Because those who never take risks don’t grow. Mistakes are not a flaw to me, but learning opportunities. Over the years, I’ve learned to quickly identify and leverage the individual strengths of my team members. The goal is always to build a strong, complementary team. I firmly believe that good leadership also means accepting others’ ideas – especially when they’re better than your own. That’s how true collaboration emerges. Despite maintaining a collegial atmosphere, I place great emphasis on professionalism. I want every team member to feel taken seriously and to know where they stand with me. Trust doesn’t come from fancy words but from attitude and actions. HOW DO YOU VIEW THE FUTURE OF SALES AT BINDER GROUP? WHAT ARE THE KEY CHALLENGES AND LEVERS? I firmly believe we’re facing a fundamental shift in sales. Customers no longer just expect individual components, but holistic solutions – including cables, assembly, and consulting. Those who offer this comprehensive service have a clear advantage. At the same time, we’re under pressure from global competition and increasing comparability through online platforms. To stand out, we must offer more: exceptional service quality, reliable products, and personal support. Sales needs to become faster, more agile, and consistently service-oriented – and that applies to the entire company. Our “new sales drive” is not a shortterm initiative but a mindset that should shape our long-term actions. When we work closely as a team, make fast decisions, and create real added value, sustainable growth is possible. Our experiences in Switzerland prove: it works. Now it is important to continue along this path throughout the entire company. As a family-owned company, we have the advantage of being flexible and quick to react. We use this strength by seeing our customers as partners, involving our employees, and staying open to change. Our focus is clear: transitioning from a pure manufacturer of circular connectors to a comprehensive solution provider. WHAT ARE THE CURRENT TRENDS IN CIRCULAR CONNECTORS? Requirements are steadily increasing – not just technically, but also in terms of handling and versatility. The trend is moving towards increasingly compact yet powerful connectors that remain robust and durable. At the same time, our customers want user-friendly solutions – for example, with tool-free assembly. Material demands are evolving as well: halogen-free materials, flame-retardant designs, and modular systems are now standard. Those who anticipate these needs and offer innovative solutions will retain customers longterm. Often, the difference lies in the details – and those who recognize and implement them early gain a competitive advantage. WHY SHOULD CUSTOMERS CHOOSE BINDER CIRCULAR CONNECTORS? Because we don’t just deliver products – we embody partnership. Our circular connectors are proven and reliable, but that alone isn’t enough. What truly matters is our attitude toward our customers. We think ahead, develop solutions proactively, and don’t offer off-the-shelf responses. For us, service means genuine accessibility – not a call center, but direct contact with decision-makers. If a customer has a problem, it becomes our problem too. binder doesn’t see itself as a mere manufacturer but as a reliable partner. Everyone on the team – from sales to logistics – lives this philosophy. The result: customers who aren’t just satisfied, but convinced, because they feel: binder sees more than just the next order – we see the importance of their interests and projects.

UL- CERTIFICATION FOR POWER CONNECTORS THE IMPORTANCE OF
VERBINDER 63 25 conductor connection. These tests significantly contribute to minimizing risks such as short circuits, fires, or failures. This is of central importance in safety-critical areas like industrial automation or power distribution. The demand for these extended certifications is market-driven. More and more industries rely on standards-compliant components to make their products safe, reliable, and globally deployable. TYPICAL APPLICATIONS AND TECHNICAL REQUIREMENTS UL-certified connectors are used in numerous industrial applications. For example, UL-certified power connectors are employed in M12 power applications. In alternating current (AC) power supply, M12 connectors with K and S coding are used, such as for frequency inverters, motor switches, or AC motors. For direct current (DC) applications, L and T-coded variants are CUSTOMERS DEMAND PERFORMANCE, DURABILITY AND COMPLIANCE WITH STANDARDS. /07 SECURE CONNECTION SOLUTIONS FOR THE GLOBAL MARKET INTERNATIONAL MARKET REQUIREMENTS AND CUSTOMER EXPECTATIONS The demands on modern connectors are continuously rising. Particularly in industrial environments, power supply, or drive technology, there is a high need for certified and high-performance connection solutions. Customers expect not only high current-carrying capacity and durability but also compliance with international standards. This is where UL certification comes into play: For many Original Equipment Manufacturers (OEMs) and system builders, it is a prerequisite to operate machinery and systems in markets like North America. A key advantage of UL-certified components is that they reduce approval hurdles, lower liability risks, and serve as a quality differentiator against competitors. FROM STANDARD TO CHALLENGE: UL2237 IN FOCUS In the past, the industry often referred to the UL2238 standard, but increasingly, the more demanding UL2237 standard is coming into focus. In addition to classic requirements like insulation and voltage resistance, additional tests are prescribed. These include the Abnormal Overload Test, which examines behavior in overload scenarios, and the Ground Bonding Test, which ensures the quality of the protective In an increasingly interconnected and regulated world with rising safety requirements, international standards and certifications, especially in technically demanding fields like industrial power supply, are gaining importance. One of the most renowned testing and certification organizations globally is Underwriters Laboratories (UL). Their standards are considered particularly stringent and set benchmarks worldwide for product safety, reliability, and compliance. For manufacturers of electrical connection technology like binder, UL certification is therefore a central component in the development and quality assurance of connectors.
utilized, proving their worth in fieldbus Ethernet components, network devices, LED lighting systems, or DC drives. Here, connectors must not only withstand high electrical and mechanical loads but also ensure reliable contact under limited space conditions. When designing and testing power connectors, several technical criteria are in focus. A central aspect is current-carrying capacity, which depends not only on conductor cross-section but must also be evaluated in combination with ambient temperature. Additionally, derating guidelines apply to ensure maximum current load under real operating conditions. Contact quality also plays a decisive role in operational safety. Connection systems must be tested both mechanically and electrically—including tested strain relief systems to minimize risks like loose contacts or material fatigue. For insulation, only UL-approved materials that meet the requirements for voltage resistance and flame retardancy according to UL 94 may be used. Last but not least, size is a critical issue, as compact designs are desired but limited by the minimum air and creepage distances defined by UL. LONG-TERM EXPERIENCE AND QUALITY COMMITMENT AT BINDER Close collaboration with UL is already standard practice for many manufacturers. For example, binder has been working with UL since 1984. The first certified series was the 693 series. Four times a year, UL conducts onsite inspections—a clear indication of the high priority given to quality and safety in the company. Fire protection requirements play a paramount role here, as they can determine the safe operation of an entire system, especially in industrial connection technology. Quality is also given top priority in manufacturing. Quality management includes monitoring compliance, supplier evaluations, comprehensive documentation, and internal audits—all critical factors for successfully implementing UL requirements. The growing demand for UL2237 is a clear signal that UL will continue to play a decisive role in the future. Manufacturers like binder are responding early to this development and are currently qualifying several products for UL2237. Customers benefit from technological advantages when using
VERBINDER 63 27 THE CONNECTORS MUST BE ABLE TO WITHSTAND HIGH LOADS AND PROVIDE RELIABLE CONTACT EVEN IN TIGHT SPACES. these products while also ensuring the long-term marketability of their own products. UL CERTIFICATION AS THE KEY TO FUTURE VIABILITY UL certification is far more than a formal proof. It is an essential building block for safety, trust, and international competitiveness. In a time of growing regulatory requirements and increasing complexity in industrial manufacturing, certified power connectors represent a reliable and future-proof solution—for manufacturers, OEMs, and users alike.
M12 L- AND T-CODED /08 binder introduces new M12 L- and T-coded connectors featuring stainless steel locking mechanisms, ensuring the highest levels of reliability and durability in demanding industrial environments.
VERBINDER 63 29 RELIABILITY IN HARSH ENVIRONMENTS In today’s industrial landscape, characterised by advancing automation and the growing need for robust and space-saving connection solutions, the M12 series from binder is establishing new standards. The new L- and T-coded connectors not only impress with their high reliability and durability, but also with their impressive resistance to extreme conditions. In view of the increasing requirements in the context of Industry 4.0, these connectors represent a cost-effective and reliable solution for signal, data and power supply in harsh environments. HIGH-QUALITY ENGINEERING IN DETAIL The 813 series (T-code) from binder is particularly suitable for applications where high electrical performance and high resistance to external influences are required. The number of poles of four and a screwable stainless steel locking mechanism result in a protection class of IP67, which guarantees complete protection against dust and temporary immersion in water. The connection is made via screw terminals, which are suitable for cable apertures of 6-10 mm, and supports a connection cross-section of up to 1.50 mm²/AWG 16. The series has a rated voltage of 63 V and a rated current of 12.0 A, which qualifies it for use in electrical systems with high requirements. The mechanical service life of over 100 mating cycles ensures a long service life. The 823 series (L-code) enables increased flexibility and performance, especially for applications with increased current requirements. The MAXIMUM DURABILITY IN HARSH INDUSTRIAL SETTINGS number of poles of 4 or 4+FE and the connection cross-section of up to 2.5 mm² / AWG 14 without wire end ferrules predestine this series for use with higher current loads of up to 16 A. The stainless steel locking mechanism also ensures high mechanical stability and IP67 protection. The wide cable aperture of 8-13 mm and the ability to work in temperature ranges from -40 °C to 105 °C make this series the ideal solution for demanding industrial environments. In electrical terms, the series has a rated voltage of 63 V.

VERBINDER 63 30 JOB HIGHLIGHTS As a product manager at binder, I particularly value the cross-departmental communication and close collaboration with various teams across the company. My daily work is characterized by an exciting mix of technical expertise, strategic thinking, and close interaction with both internal and external partners. The strong network with other manufacturers, customers, and suppliers allows me to identify market requirements early and translate them into innovative product solutions. It’s precisely this diversity and the interface function of my role that make my job so special and rewarding. THE JOB IN THE FUTURE I am convinced that the role of the product manager will change significantly in the coming years—especially due to the growing influence of digitalization and artificial intelligence. Processes will become more automated, decisions more data-driven, and the demand for agile, technology-supported solutions will continue to rise. At the same time, it will become increasingly important to pursue innovative approaches and strategically develop products holistically—from the initial idea to international market entry. Therefore, I see the future of the profession not only in the efficient management of product lifecycles but above all in actively shaping intelligent, user-centric solutions that are geared toward global competition.
CHALLENGES IN THE JOB A central issue is the increasing global competitive pressure, particularly due to declining prices. To remain competitive in the long term, processes must be further automated, and new, more cost-efficient manufacturing locations abroad may need to be considered. These strategic considerations require foresight, cost-effectiveness, and an innovative mindset. APPLICATIONS Our connectors are used in a wide range of industries—from sensor technology and measurement systems to conveyor and storage systems, robotics, automated guided vehicles (AGVs), and even in the military sector, such as in functional equipment or reconnaissance drones. Their versatility makes them an indispensable component of modern technologies. PRODUCTS OF THE FUTURE I am convinced that the future of connection technology lies in modular, smart, and hybrid connectors. Modular connectors offer maximum flexibility thanks to their building-block principle: they can be individually tailored to customers’ specific requirements, enabling customized solutions for a wide variety of applications. Another promising trend is smart connectors. By integrating circuit boards, measurement electronics, or Bluetooth interfaces, these connectors become “intelligent.” They can detect, analyze, and even initiate countermeasures in case of malfunctions—a crucial step toward predictive maintenance and process reliability. Last but not least, I see great potential in hybrid connectors. They combine power, data, and signal transmission in a single connector—saving not only space and weight but also significantly simplifying system architecture. WHAT MAKES OUR PRODUCT MANAGERS UNIQUE I would say it’s the combination: I am honest, empathetic, enjoy making decisions, and am absolutely reliable. When I set a goal, I pursue it with determination and perseverance. Humility is important to me because I believe good work should speak for itself. What am I particularly good at? Others should judge that. I simply try to do my best every day and perform my role as a product manager with dedication, clarity, and a strong sense of responsibility—with the goal of developing meaningful products and making an impact together as a team. BEING A PRODUCT MANAGER AT BINDER MEANS … … taking responsibility—not only for the strategic development of our product portfolio but also for the daily, collaborative work with colleagues. It means being a team player who builds bridges—between departments, interests, and ideas. Only through shared exchange can we create sustainable solutions that meet our high-quality standards while keeping our customers’ needs in focus. A respectful, equal-level interaction is particularly important—whether in the meeting room or directly on the production floor. Because true innovation only happens when all perspectives are heard and valued. /09 INTERVIEW GUIDO WERNER
32 | VERBINDER 63 WHAT IS CHANGING? The European RoHS Directive (Restriction of Hazardous Substances, 2011/65/EU) regulates the restriction of certain hazardous and toxic substances in electrical and electronic equipment. Its aim is to minimize environmental and health risks that may arise from the use of toxic materials. Until now, an exemption allowed the use of lead in copper alloys (up to 4% by weight) – particularly for robust components such as connectors, bearings, or valves. The reason: lead-containing alloys offered good workability, corrosion resistance, and mechanical strength. However, this Exemption 6c is now expiring. After multiple extensions, the EU Commission no longer sees a justification for continuing it – lead-free alternatives are now technologically mature. For manufacturers, this means: from the effective date onwards, no new products containing leaded copper alloys may be placed on the market unless a specific exemption applies. As a result, many companies now face the challenge of adapting their production and qualifying alternative alloys. Many companies are therefore being forced to modify their manufacturing processes and to qualify and implement suitable lead-free alloys. LEAD AND ROHS ANNEX 3 EXEMPTION 6C /10
VERBINDER 63 33 THE REMOVAL OF LEAD FROM ELECTRICAL AND ELECTRONIC EQUIPMENT OFFERS SIGNIFICANT ADVANTAGES: 1. REDUCTION OF TOXIC WASTE Lead is a persistent heavy metal contaminant. It does not break down in the environment but accumulates in soil, water, and living organisms. During recycling or improper disposal of electronic waste (e.g., in landfills or through illegal exports), lead can be released into the environment, causing long-term damage – with lasting consequences for ecosystems. 2. PROTECTION OF HUMAN HEALTH Lead is neurotoxic, especially to children. Even small amounts can impair cognitive development, lower intelligence, and negatively affect behavior. Adults, too, can suffer kidney damage, cardiovascular issues, or reproductive harm from chronic lead exposure. Workers involved in melting, casting, or machining lead-containing alloys are directly at risk – lead-free processes significantly reduce this danger. 3. SUSTAINABLE CIRCULAR ECONOMY The adoption of lead-free alloys improves the quality of the recycling stream. Materials from old devices can be reused more easily and safely. Lead-free products enhance the overall environmental footprint of electronic devices throughout their entire life cycle. CONCLUSION The end of Exemption 6c marks an important step toward a non-toxic, greener electronics industry. While the transition poses technological challenges, the long-term benefits for the environment, recyclability, and human health clearly outweigh them. Companies that adopt lead-free alternatives early are actively contributing to environmental protection and positioning themselves for long-term success in an increasingly sustainability-focused market.

34 | VERBINDER 63 PATENTS, TRADEMARKS, DESIGNS – THE TOPIC OF INTELLECTUAL PROPERTY IS COMPLEX AND HAS CHANGED SIGNIFICANTLY OVER TIME. BUT WHAT EXACTLY IS BEHIND THE SO-CALLED IP DEPARTMENT AT BINDER? In the past, people usually referred to it simply as the patent department – a small unit whose task was to register and manage property rights and defend them when necessary. But those days are long gone. Today, the IP team (T-PI) is much more than that. FROM PROTECTION RIGHTS TO STRATEGY “In the past, the focus was primarily on protecting our developments. Today, we actively shape how binder handles intellectual property: strategically, operationally, and across disciplines,” explains Michael Finke, responsible for IP management at binder. Demands have increased. Risks from legal disputes, complex international markets, and rising innovation pressure make holistic IP management indispensable. binder has recognized this shift and is actively shaping it: Based on the DIN 77006 standard, structures have been created to modernize and integrate IP work across the company. PART OF THE WHOLE: IP IN THE PRODUCT DEVELOPMENT PROCESS Today, the IP team is involved in many core processes – from product development and risk management to innovation workflows. Decisions are made based on the IP strategy. The goal is to legally safeguard business operations, maintain freedom to operate, and contribute to the company’s long-term success. RETHINKING INTELLECTUAL PROPERTY /11 HOW THE IP TEAM WORKS AT BINDER
Michael Finke has been with binder since 1999 and is the team leader in the Patent and Innovation Management department. ABOUT THE AUTHOR THREE LEVELS, MANY TASKS The work of the IP team can be broadly divided into three levels: Strategic: Defining the company’s direction regarding intellectual property. This includes implementing DIN 77006 and shaping the employee invention system. Operational: Concrete implementation, such as integrating IP processes into the binder management system (bms), supporting innovation management, processing invention disclosures, and monitoring third-party activities – a key aspect to identify potential conflicts early. Administrative: Ensuring that all IP-related activities are documented in a structured and traceable manner. Central databases, standardized procedures, and digital folder structures guarantee transparency and efficiency – also with the help of external service providers. IP AT BINDER: A PARTNER, NOT JUST AN ADMINISTRATOR “We see ourselves as partners within the company for all matters relating to intellectual property,” says Finke. This is evident not only in the technical work but also in the close collaboration with other departments. Do you have questions about intellectual property or innovation? The IP team looks forward to hearing from you – by phone at -245 or by email at m.finke@binder-connector.de.
