Gold-plated male pins with 8.00 µ" (0.203 µm) thickness handle low-cycle mating in controlled environments; the latch lock holds the pair mated against vibration in an enclosure. This is a free-hanging (in-line) plug, so it lands on the wire harness end, not the board.
Termination and mating — what the IDC and latch mean on the bench
That saves assembly time on a harness board, but the wire must be solid or stranded with a tight strand count; the IDC slot is sized for the 2.00 mm pitch, so the insulation jacket can't be thick-jacketed. The latch lock snaps over the mating header's ramp — you'll hear it seat. No secondary lock here, so the latch is the only retention. The 8 µ" gold flash is enough for a few dozen mate cycles in a clean cabinet; if this plug sees repeated field disconnect, step up to a thicker-gold variant in the RITS family.
