A D-coded M12 plug that seals at the panel face
This TE Connectivity T4141512051-000 is a 5-position M12 plug with female sockets, built for a threaded bulkhead mount through the panel and soldered to a PCB. The D-coded keying — orientation D — means it only mates with a D-coded receptacle, keeping power or data pairs from crossing with A- or B-coded sensor lines on the same machine. The nickel-plated copper alloy shell and the gold-plated contacts (3.00 µin gold over nickel on the mating surface) are rated for 4 A per contact at 60 V, with an IP67 seal when mated — dust-tight and protected against temporary immersion. The bulkhead mount uses a front-side nut to clamp the connector to the panel, and the solder tails run through the PCB — a common layout for control I/O modules where the connector body takes the cable strain, not the board.
What the 4 A and IP67 ratings mean on a D-coded M12
Rated 4 A per contact at 60 V in the M12-5 shell size. The 3.00 µin gold flash handles field-service mating cycles. IP67 rating covers dust ingress and temporary water immersion. The seal relies on the O-ring at the panel face.
