The 87631-4: It is a free-hanging (in-line) housing designed for crimp-terminated female socket contacts, with a detent lock that holds the mating header in place without a secondary latch. The black thermoplastic insulation is rated for -65°C to 105°C, covering most industrial, automotive, and telecom environments. This is the housing-only shell — the contacts are ordered separately, so the BOM needs the matching crimp terminal line item.
Mating and Contact Fit
This receptacle mates with the matching AMPMODU Mod IV 0.100" pitch header — the detent lock engages with the header's locking ramp. The housing accepts crimp female socket contacts (not included).
