M12 B-Coded Plug for Panel-Mount Sensor Networks
The TE T4131412051-000 is a 5-position M12 B-coded plug with female sockets, terminated via solder cup and designed for panel mounting with a bulkhead front-side nut. The B orientation keying prevents accidental mating with A-coded (sensor/actuator) or D-coded (Ethernet) M12 connectors — it is the standard interface for fieldbus and DeviceNet trunk lines where the pin assignment follows the B-code layout. The nickel-plated copper alloy shell and polyamide insert carry an IP67 rating when mated, sealing against dust ingress and temporary water immersion up to 1 metre for 30 minutes.
Mounting and Sealing
The threaded fastening type locks the mated pair positively; in a vibration environment the thread engagement keeps the connection tight without a secondary locking clip. The unshielded shell means this plug does not carry a cable braid termination — for shielded cable runs, the mating receptacle should handle the shield bond.
Listed as Active on the TE product lifecycle — this is a current-production part, not a last-time-buy or NRND line.
