Board-fit and mating half
The 1-177537-0: This is a 10-position, single-row header on 2.50 mm pitch, through-hole mounted, with a shrouded 3-wall design that guides the mating plug and prevents misalignment. The friction lock holds the pair together under moderate vibration — a practical detail for harness builders who want a positive retention without a secondary latch. Termination accepts both press-fit and solder — the press-fit option suits solderless backplane assembly where rework or high-reliability is a concern. Contact finish is tin on both mating and post sides, rated for general-purpose environments within -25°C to 105°C.
