What does the coding mean on M12 connectors?

M12 connectors are circular connectors with a 12-mm locking thread used for sensors, actuators, Fieldbus and industrial Ethernet, primarily in factory automation applications. Often with ratings ofIP65, IP68 and IP69K, they are ideal for wash down and corrosive environments.


The M12 family can be found in many applications such as factory automation, measurement and control, communications, food and beverage, transportation, agriculture, robotics and alternative energy.


When it comes to specific applications, users must select the right pin count. For sensors and power applications, 3 and 4 pins are required. Profinet and Ethernet use 4 and 8 pin counts. And Fieldbus, CANbus and DeviceNet primarily use 4 and 5 pin counts. Finally, specify 12 pins for signal requirements.


Several styles of coding exist in M12 connectors. This coding prevents incorrect mating on products. In addition, shielding is available in most coded M12 connectors. For example, X-coded connectors are specifically shielded by the design of their coding.
