M12 A-coded Connector Core Count & Application Scenarios

Standard Core Count Range

  • Universal Specification: Full coverage of 2~17 cores, different core counts are matched with different transmission requirements for industrial use

Core Count Classification & Application

2 ~ 4 Cores

Focus on low-power power supply transmission, suitable for power connection of industrial sensors, small actuators, single-signal transmission equipment.

5 ~ 8 Cores

Dual transmission of power and signal, the mainstream core count specification, adapted for encoders, proximity switches, photoelectric sensors in industrial automation.

9 ~ 12 Cores

Multi-channel signal acquisition and transmission, suitable for multi-path sensor integrated modules, centralized control small terminal equipment, multi-signal collection units.

13 ~ 17 Cores

High integration comprehensive wiring, for complex industrial control systems, robot joint modules, high-density integrated equipment with mixed power and multi-signal.

Technical Note: M12 A-coded is the most widely used pin definition standard for industrial sensors, the core count selection is based on the actual number of power supply and signal channels of the equipment, avoid blind selection of large core count to cause cost waste.
