M12-D4 Molded Circular Connector, 4-pin D-coded, designed for industrial Ethernet applications. Features IP67 protection rating and one-piece molded construction. Supports 100Mbps data transmission; suitable for field wiring of PROFINET, EtherCAT, and other industrial Ethernet protocols. M5, M8, and M12 circular connectors are industry-standard threaded waterproof aviation plugs used in automation. Protection ratings reach IP67 to IP68; widely used for sensors, actuators, industrial I/O, robots, and device signal/power connections. Available as pin-type male (P) or socket-type female (S), with shielded (SH) and unshielded (NS) versions. Support soldering or crimping termination. Offer both molded complete plugs and assembled components in straight and angled configurations. M5 is ideal for signal transmission in compact spaces; M8 is commonly used for proximity and photoelectric switches; M12 supports signals, power, and industrial Ethernet communication. Gold-plated contacts resist vibration and oil contamination. Select shielded versions for EMI-prone environments; choose unshielded for standard indoor applications to reduce costs. Compatible with on-site assembly and mass harness production.
