M12 D-Coded Plug, 3 Positions, 4A, IP67 — Panel-Mount with Board Locks
The TE Connectivity T4145535031-001 is a 3-position M12 plug with female sockets, D-coded, rated 4A per contact at 250V. It is a shielded, IP67-sealed panel-mount connector with a right-angle PCB tail, terminated by soldering. The nickel-plated copper alloy shell gives it a silver appearance, and the insert is glass-filled PA66. Unusually for an M12 plug, this variant includes a Board Guide and Board Lock — features that anchor it to the PCB during assembly and resist vibration shear, making it a fit for industrial sensor or actuator interfaces where the connector is part of a control board assembly rather than a free-hanging cordset.
D-Coding and 3-Position Pinout — What Fits
The D-coded orientation means the keyway is rotated 180° from A-coded — a D-coded M12 plug will not mate with an A-coded receptacle, which prevents cross-wiring on Profinet or Ethernet/IP networks where D-coding is standard for 100 Mb/s data pairs. The 3-position shell size is M12-3, which accepts three female socket contacts.
IP67 Sealing and Operating Range
Rated IP67 when mated with the matching D-coded receptacle — the O-ring seals at the panel face, not the thread, so the seal depends on the bulkhead nut being torqued correctly. The 4A per-contact current rating at 250V is typical for M12 signal and low-power data connectors; derate above 85°C per the manufacturer's curve.
