What this 3-position shrouded header does
The 2342071-3 is a 3-position, single-row shrouded header from TE Connectivity AMP Connectors, pitched at 0.138" (3.50mm) — a common spacing for wire-to-board power and signal applications where the board needs a polarized, protected pin field. The vertical through-hole orientation and 0.075" (1.90mm) solder-tail length suit standard PCB thicknesses.
At 3.50mm pitch, the three pins occupy a board footprint about 7mm wide — the shrouded walls add a few mm on each side. The 0.362" (9.20mm) insulation height leaves room for the mating receptacle housing to engage fully. The 4-side shroud prevents mis-mating with a non-keyed plug.
