The 1-292132-0: This is a 10-position, single-row vertical header on 2.00 mm pitch — the footprint eats 18 mm of board edge plus the shroud overhang. The 0.126 inch (3.20 mm) solder tail length suits standard 1.6 mm PCBs; the kinked pin provides a press-fit retention in the plated hole before wave solder.
Detent lock keeps the mate from walking loose
The detent lock (a molded ramp on the shroud that clicks into the mating housing) holds the pair together under light vibration or cable tug — it's not a latch you can hear from across the room, but it resists the kind of fretting that opens a tin-tin interface over time. Mates with the matching TE CT series receptacle housing and crimp terminals — the lock feature is on the header side, so the receptacle just needs the standard detent window.
