What This Housing Does in the Harness
The 1-962340-1: The housing is black PBT (polybutylene terephthalate), a common insulation material that holds up to moderate heat and vibration in industrial or automotive harnesses.
This housing mounts with a panel snap-in feature — push it into a rectangular cutout and the barbs lock it in place, no hardware needed. Termination is crimp-style: you buy the mating tab contacts separately (the housing ships empty). The single-row, 4-position layout keeps the harness narrow, useful for tight routing in a junction box or appliance panel.
