M-Series Connectors for Industry 4.0 and Smart Manufacturing
Industrial automation is the core application field for M-Series circular connectors. From traditional PLC control and sensor signal transmission to modern industrial robots, servo drives, and machine vision systems, M5/M8/M12 connectors — compliant with IEC 61076-2, rated IP67/IP68, and configurable from 3 to 17 contacts — have become essential components on automated production lines.
M8/M12 A-coded 3–5 pin connectors are the most common interface for industrial field sensors (photoelectric, proximity, temperature, pressure) and actuators (solenoid valves, cylinders, motors). IP68 rated, -25~+85°C wide temperature range, and vibration-resistant design ensure reliable operation in oil mist, dust, and humid workshop environments.
M12 D-coded (4-pin, 100 Mbps) and X-coded (8-pin, 10 Gbps) connectors serve as the standard interface for PROFINET, EtherCAT, EtherNet/IP, and Modbus TCP industrial Ethernet protocols. A-coded and B-coded M12 connectors support Profibus, DeviceNet, and CANopen fieldbus systems.
M12 K-coded and L-coded power connectors handle power and signal transmission for servo drives and variable frequency drives (VFDs). 5-pin 4+PE design, rated up to 16A / 630V, meeting high-power drive requirements. Shielded design provides EMI/EMC protection.
