M8 Male Plug for Sensor and Actuator Networks
The TE Connectivity T4040014031-000 is a 3-position, A-coded M8 male plug designed for the rugged end of factory automation and industrial control wiring. It is the male half of a circular, threaded-coupling interconnect — the kind you find on proximity sensors, photoelectric eyes, and valve manifolds where a vibration-proof, sealed connection is non-negotiable. The 3 A per contact rating at 60 V covers both signal-level sensor feedback and low-power actuator drive on the same connector body. The M8-3 shell size is the standard mechanical interface for 3-pin M8 connectors, meaning it mates with any M8 A-coded female receptacle or cordset that follows the IEC 61076-2-104 footprint. The A-coding keyway prevents cross-mating with B- or D-coded M8 connectors, so you don't accidentally plug a sensor line into a fieldbus port. Gold plating on the mating contacts (3.00µin) is the right call for this duty — it keeps contact resistance stable across the rated -40°C to 85°C range and through the hundreds of mate/unmate cycles a field-serviceable connector sees. Tin contacts would corrode in the condensation cycles common in unheated industrial cabinets.
IP67 Sealing and Threaded Coupling — Where It Works
The IP67 rating means this plug is dust-tight and survives immersion in 1 meter of water for 30 minutes when mated with its IP67-rated female counterpart. That makes it a fit for washdown zones in food processing, outdoor conveyor systems, and any panel where a coolant spray or hose-down is part of the maintenance cycle. The threaded coupling (M8 x 1.0 thread) is what keeps the connection tight under machine vibration. A push-pull latch would rattle loose on a robot arm or a vibrating pump skid; the screw-lock ring holds the pair mated until you deliberately unthread it. The nickel-plated copper alloy shell handles the mechanical load and provides a continuous shield path through the connector body. Termination is solder-cup — you tin the wire, insert it into the cup, and solder. This is the standard field-termination method for M8 connectors when you are building custom-length cables rather than buying pre-molded cordsets. The panel mount with bulkhead feature lets you fix the plug to a panel wall with the threaded nut, creating a fixed equipment port.
