Connector Pinout
Standardized connectors are used to connect actuators, sensors, control units to lines even if devices are from different manufacturers. Exact technical specifications of the connectors guarantee that parts can be combined or replaced where it may be reasonable. Screw and plug connectors of voltage lines are designed to avoid being confused with one another. Incompatible plugs and sockets can’t be connected in most cases. This ensures the operability of circuits and avoids damage to control units, terminals and lines. Additionally the higher level types of connectors are split up into numerous types additional links. Theses again are set up to be not able to connected despite a similar outer appearance. Thus the choice of connectors is diverse. The wide bandwidth assures a maximum of operation safety for each desired assembly. Three widely known types of connectors are RJ45 plug connectors, M8 plug connectors and M12 plug connectors.
RJ45 plug connectors
M8 Plug Connectors
M plug connectors are screwed tight together. In addition they contain inside seals which makes them water and dust resistant. Due to this M plug connectors are often IP65 classified. By defaultM8 plug connectors are euqipped with 3 or 4 poles. The 3-pole-variant is exclusively responsible for signal transmission of sensor lines. The 4-pole-variant can also serve for actuators with a low preload which are limited to 60 V for the M8 plug connector. It is not recommended to use this full voltage range. For safety reasons it may be advisable to use an M12 plug connector instead of an M8 plug connector when getting close to the maximum voltage allowed for such. Here you can find further information regarding the pinout of M8 plug connectors.
Product OverviewM12 plug connectors
M12 plug connectors are equipped with a screw connection similar to M8 plug connectors. It offers the same connection safety. Additionally M12 plug connectors are available in a much wider bandwidth variety. It is one of the most versatile groups of connectors in electric connection technology. Today M12 plug connectors are available up until voltages of 600 V. Due to this range and the compact design in most industry branches this is the connector of choice. Here you can find additional information regarding the pinout of M12 plug connectors.
