M12 A-Coded Panel Receptacle — 4-Pin, IP67, Gold Contacts
The T4171210004-001 is a 4-position M12 A-coded receptacle with male pins, built for sealed industrial interconnect where a threaded, vibration-proof mate is required. The housing is metal (copper alloy with nickel shell finish), the insert is UL94 V-0 rated polyamide, and the mating contacts are gold flash over copper alloy. This is a panel-mount design using a bulkhead rear-side nut, with wire leads for termination — no PCB footprint to worry about, just a panel cutout and a threaded nut. The A-coding orientation means it mates only with A-coded M12 plugs, which is the standard pinout for sensor/actuator networks and DC power distribution in industrial automation.
What the 4A Rating Means for the Fit
4A per contact at 250V is the standard current density for an M12 size-4 connector. This is sized for sensor power, actuator solenoids, or low-current DC distribution, not a motor drive. The IP67 seal means the connector can be washed down or exposed to rain — common on conveyor lines, packaging machinery, and outdoor cabinet interfaces. The UL94 V-0 nylon insert meets the flame rating required inside industrial control panels. If the application needs higher current per pin or a different coding (D-coded for Ethernet, B-coded for fieldbus), this A-coded 4-pin is the wrong pick — it's purpose-built for sensor/actuator and low-power DC circuits.
