The 1744429-4 is a 4-position, single-row header from TE's Economy Power series, pitched at 3.96mm (0.156-inch) — a spacing common in industrial power and lighting circuits where you need room for 7.5A per contact without crowding the board. It's a shrouded 1-wall design with a friction lock, so the mating receptacle stays put under vibration without needing a screw or latch.
