Three-Position Plug Housing for Signal Mate Harnesses
The latch lock clicks into place on the header shroud, giving vibration resistance that a simple friction lock won't provide. Termination is crimp-style: you insert the correct female socket contact (sold separately) into the cavity until the retention tang seats, then push the terminal fully home. The PA66 housing is glass-filled for dimensional stability under the crimp insertion force and during temperature cycling.
3 vs 6 Positions — Same Series, Different Circuit Count
The 1376477-3 is the 3-position member of the Signal Mate plug housing family. The closest sibling in the same series is the 1-1376477-6, a 6-position plug housing in red PA66 with the same 2.50 mm pitch, single-row layout, latch lock, and crimp termination. Choose the one that matches your BOM line count — the footprint and mating header are otherwise identical.
