The degrees of protection according to IEC60529 apply to various articles and provide information on protection against the intrusion of water and solids such as dust.
IP40Protects against contact with tools, wires and other similar objects of Ø > 1 mm and against the intrusion of foreign bodies of Ø > 1 mm. Does not protect against water.
IP67Fully protects against touch and against the intrusion of dust. Protects against water intrusion in temporary immersion (depth: 1 m; duration: 30 minutes).
IP67 when unplugged as wellFully protects against touch and against the intrusion of dust. Protects against water intrusion in temporary immersion (depth: 1 m; duration: 30 minutes).
IP68Fully protects against touch and against the intrusion of dust. Protects against water intrusion in sustained submersion (depth: 2 m; duration: 24 hours), requirements specification by agreement between producer and user.
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.
DistributorIn distributors, an input current or signal is distributed over multiple outlets according to a particular wiring logic. The locking system/termination for the input may differ from that for the outlet.
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.
MiniatureConnectors with an external diameter of 16–21.5 mm and various locking systems.
