M12 B-Coded Panel-Mount Plug, 4-Position Female Sockets
The T4141412041-000 is a metal-shell M12 plug with 4 female sockets, B-coded orientation, and a threaded coupling nut. It mounts through a panel hole and secures with a front-side nut — the IP67 seal is at the bulkhead face, not the thread, so the O-ring compresses against the panel surface when the nut is torqued. The shell is nickel-plated copper alloy; the insert is PA66 rated UL94 V-0.
IP67 Sealing and Panel Fit
IP67 Dust Tight and Waterproof means the mated pair survives immersion at 1 m for 30 minutes — but the seal depends on the O-ring at the panel face. The bulkhead nut compresses the O-ring against the panel; the panel hole must be clean and burr-free for the seal to hold. No separate gasket is listed; the O-ring is integral to the connector body.
B-Coding and Mating Compatibility
B-coded M12 connectors are keyed for fieldbus and industrial Ethernet applications — the keying pin position prevents mating with A-coded (sensor/actuator) or D-coded (PROFINET) receptacles. This 4-position plug mates with any standard B-coded M12 panel-mount or cordset receptacle of the same shell size (M12-4). The threaded coupling nut provides vibration-resistant retention per IEC 61076-2-101.
