The TE Connectivity 5-1971793-1 is a 5-position, single-row plug housing from the Grace Inertia, GIC series. It uses a 2.50mm pitch and a latch-lock fastening system, so it mates positively without tools and stays locked under vibration — a common failure point in field-service harnesses where a backed-out terminal stalls a line. The housing is natural-colored polyamide (PA66) rated for -30°C to 105°C, which covers most industrial cabinet and under-hood automotive environments. It accepts female socket contacts terminated by crimp, but the contacts themselves are not included — you order them separately against the wire gauge and current need.
The contacts trap — what to order alongside it
Contacts are not included with this housing. Order Grace Inertia GIC female socket crimp terminals separately for the wire gauge you need.
