The TE Connectivity 1740825-1 is a 2-circuit plug housing from the Nector S series, designed for Cable/Wire to Cable/Wire or Board interconnects. It accepts socket contacts via crimp termination and mounts free-hanging (in-line), making it a straightforward choice for harness-to-harness or harness-to-board power or signal runs that need a keyed, polarized interface. Rated at 250V, the housing suits low-to-moderate voltage circuits common in industrial control, appliance wiring, and automotive auxiliary harnesses. The keying HV-4 feature ensures the plug mates only with the corresponding receptacle keyed HV-4, preventing cross-mating with other Nector S keying variants in a multi-connector assembly. The white housing colour and bulk packaging are typical for high-volume harness builds where visual identification of keying helps on the line.
This plug housing mates with a Nector S receptacle housing (or header) that accepts pin contacts and carries the complementary HV-4 keying. The crimp termination means the socket contacts are installed into the housing after being crimped onto the wire — field-serviceable without solder. The free-hanging mount allows the connector to float in the harness, absorbing vibration and simplifying routing in tight enclosures.
