Crimp pin for Mini-Universal MATE-N-LOK housings
It's a tin-plated phosphor bronze crimp terminal sized for 18-22 AWG wire — the stamped construction keeps the contact cost-effective for high-volume harness production while the tin finish suits moderate mating-cycle duty in dry indoor environments. This is the male half that goes into the receptacle housing; the matching socket contact is the 170365 series.
Wiring and termination fit
The 18-22 AWG wire range covers common signal and low-power circuits in appliance and automotive harnesses. Tin plating on phosphor bronze gives adequate conductivity for the current these wire sizes carry, typically a few amps per circuit in the Mini-Universal MATE-N-LOK system.
