The 2232043-7: This is a 7-position, single-row header on 5.00 mm pitch — the footprint takes a 0.197-inch grid, and the through-hole posts are 0.138 inch long. The 4-wall shroud and latch holder mean the mating receptacle needs a matching latch ramp; it's a board-to-cable/wire connection, not a free-hanging splice.
Rated 250 VAC — that's line voltage for industrial control panels and power supplies. The -40°C to 120°C operating range covers unheated enclosures and cabinet interiors near warm components.
