M12 Connector

Decoding M12 Connectors

M12 connectors are distinguished by their 12mm locking thread and are engineered to withstand demanding industrial environments. They offer solutions for power, signal, and data transmission with various coding options to prevent mismating and ensure device compatibility. Here’s a quick overview of the M12 coding system:


  •  A-coded: Ideal for sensors, actuators, and DC power.
  •  B-coded: Best suited for fieldbus connections.
  •  D-coded: The choice for industrial Ethernet and Profinet.
  •  X-coded: High-speed data transmission, including Gigabit Ethernet.
