Panel-Mount M12 Plug with Wire Leads — B-Coded 4-Position
The T4171110404-001: It is the B-coded variant of the M12 series, meaning the keying orientation prevents accidental mating with A-coded (sensor/actuator) or D-coded (Ethernet) receptacles on the same panel — a deliberate selection for applications where coding discipline matters. The metal shell carries a nickel finish over copper alloy, with a bulkhead front-side nut for panel mounting through a cutout. The IP67 seal — dust-tight and waterproof — suits this plug for washdown zones, outdoor enclosures, and wet industrial environments.
Wiring and Termination — What the Wire Leads Mean for the Harness
This plug terminates to wire leads, not a PCB footprint or screw terminal — the leads exit the rear of the insert and are intended for direct soldering or crimping into a junction box, sensor head, or control cabinet. The wire leads eliminate the need for a separate field-attachable connector body, reducing the parts count in a harness build.
