The choice of version allows the definition of certain technical specifications – for example the type of cable outlet or the size.
AdapterConnecting element to each side of which a connector can be attached. This enables the realisation of, for example, control cabinet lead-throughs or a transition from the M8 to the M12 locking system.
Connecting cableConnecting cable in various pin and socket versions.
Electromagnetic compatibility (EMC) means that a connector is shielded or shieldable. This is required when it is necessary to protect the signals or data conducted by the connector, as well as to protect external devices, from disturbance due to electromagnetic effects.
Automation TechnologyAdvancing digitisation and current manufacturing technologies make possible ever smaller and more high-performance elements in the areas of sensor technology and networking. Here, sensor technology means the detection of physical values and their conversion into electric values. These electric values are converted into a digital signal that can be transmitted by means of bus communication to other bus devices. This will make automated production more modular and flexible in the future, with a preference for standardised connectors like the models M8 and M12. The worldwide availability of the connectors and their adaptation to a broad range of applications have already led to numerous versions, e.g. codings.
To avoid mismating, the connector elements – the pin and socket – must be brought into form-fitting alignment with one another (coding) before being locked.
M12-DThis coding was developed as a 4-contact, shieldable connector and standardised in accordance with DIN EN 61076-2-101 as one of the first for fieldbus wiring – e.g. PROFINET. It is used for data transmission at rates of up to 100 Mbit/s. Data transmission is becoming ever more prevalent and thus increasingly important.
