The M12 3-pin board end plug is the enclosure-side half of a standard M12 A-coded connection. Its M12×1.0 male thread sits on the outside of control cabinets, sensor housings, IO modules and edge gateways, while the rear tail is fixed directly onto the internal PCB through 180° DIP pins or solder cups — no intermediate terminal block, no internal splice, no hand wiring.

Mated with any standard M12 3-pin female cordset, the panel penetration holds IP67 sealing against dust, rain, coolant splash and oil mist. Built to IEC 61076-2-101, the interface interchanges with Phoenix, Turck, TE, Molex, Balluff and Binder M12 3-pin cordsets.

• 3-pin A coding guarantees correct polarity and blocks mis-mating on the line
• Board end fixation removes one connector pair and up to 40% of harness parts
• Gold-plated phosphor bronze contacts keep contact resistance at ≤5 mΩ
• 4A / 250V rating carries sensor, actuator and small solenoid loads directly
• Front, rear and 4-hole flange mounting with 180°/90° PCB tail options
• Nickel-plated brass shell with PA66 insulator withstands vibration and washdown
• Receptacle stays on the cabinet during board RMA, cutting field service time

• Against PG gland plus terminal block: sealed and keyed interface with half the assembly steps
• Against RJ45 / USB panel jacks: threaded lock survives vibration, hose-down and oil mist
• Against pre-wired feed-through: the PCB tail allows wave-solder and SMT line integration
• Against M8 3-pin: same 3-pin layout with higher current headroom and a stiffer shell

• Sensor and actuator interfaces on PLC, DCS and distributed IO cabinets
• Industrial networks: PROFIBUS, DeviceNet, CANopen, IO-Link 3-wire runs
• Machine vision, robotics and industrial camera trigger lines
• Charging pile, BMS and battery pack control boards
• Outdoor edge gateways, weather stations and washdown equipment
