2mm pitch, 2-position wire-to-board header
The 3-1971032-2: This is a 2-position, single-row header from the Grace Inertia GIC series, with a 0.079" (2.00mm) pitch — the standard spacing for compact wire-to-board interconnects in industrial and appliance control boards. Full 4-wall shrouding and a latch holder mean the mating receptacle clicks into place and stays there — you should hear it latch.
