The 770275-1: It accepts male or female crimp contacts (sold separately) and uses a detent lock for positive retention when mated with the matching receptacle.
Contacts Not Included — What You Need to Order
This housing ships empty. The listing note is explicit: Contacts Not Included. You will need to source the matching crimp terminals separately — the series accepts both male and female contacts, so pick the gender that matches your circuit. The crimp termination means you can terminate wires in the harness shop and then stuff them into the housing; no soldering required.
Mating and Termination
Mates with the matching Commercial.062" Pin and Socket receptacle housing (same series, opposite gender). The detent lock clicks into place and holds the pair together under moderate vibration — no secondary latch or screw lock needed. Free-hanging (in-line) mounting means this housing lives in the middle of a wire harness, not on a panel or PCB.
