It's a free-hanging (in-line) connector meant for crimp-terminated contacts — you supply the male pin terminals separately, as the housing ships empty. The black PBT insulation handles -30°C to 105°C, putting it in range for underhood automotive or industrial cabinet service where the temperature swings are real. Mates with the corresponding EconoSeal J Mark II 070 plug housing (look for the locking ramp feature on the plug side).
This receptacle housing accepts male pin contacts that you crimp onto the wire, then insert into the cavity. For a 2-position, single-row layout, the wire routing is straightforward: two individual leads, no row staggering to manage. The free-hanging design means it's a field-replaceable splice point, not a board-mounted header.
