M12 B-Coded Plug for Sealed Industrial Sensor Networks
The T4145415041-001: The B-coding matches the PROFIBUS and DeviceNet pinout convention, so this plug mates only with a B-coded receptacle, preventing accidental cross-connection with A- or D-coded M12 ports on the same panel. Gold flash on the mating contacts handles the moderate mating cycles typical of field-replaceable sensor drops.
Sealing and Environmental Range
Rated IP67, the connector is dust-tight and waterproof against temporary immersion.
This plug mounts through a bulkhead panel and terminates via right-angle solder tails to a PCB. The board guide and board lock features align the connector during wave-solder assembly and hold it in place against the shear force from the mated cable.
Electrical Ratings and Contact System
Each contact is rated 4 A at 250 V, with the current limit set by the contact beam cross-section and the housing temperature rise at the 85°C ceiling. The copper alloy contacts carry gold flash plating on the mating surface — adequate for the moderate insertion cycles of a field-serviceable sensor connector, though not intended for thousands of mate-unmate cycles. The unshielded shell means this plug relies on the system cable's own braid for EMI protection; specify the shielded version if the harness runs near variable-frequency drives or switching power supplies.
