M12 A-Coded Panel-Mount Receptacle, 4-Position Male Pins
The T4140012041-000 is a M12 A-coded receptacle with male pins, 4 positions, in a metal shell with nickel finish. It mounts panel-side via a bulkhead front-side nut and terminates through-hole solder to the PCB. The A-coding orientation and M12-4 shell size lock the mating pair — an A-coded plug is the only mate that fits, so no keying mismatch on the line. Rated 4 A per contact at 250 V, with gold-over-nickel plating on the mating surface at 3.00 µin (0.076 µm) — thin flash, adequate for the moderate mating cycles of a panel-mount interconnect that gets connected at install and stays. The IP67 seal (dust-tight, waterproof) means this connector lives in washdown zones, outdoor cabinets, or anywhere splash is a risk, as long as the mating half seals the O-ring at the panel face. Operating range from -40°C to 85°C, with a UL94 V-0 polyamide (PA66) insert — the nylon 6/6 holds up to the thermal cycling of an industrial enclosure without softening.
