2.50mm pitch, 2-position, friction-lock header for wire-to-board
The 177537-2: The shrouded 3-wall housing with a friction lock keeps the mating connector engaged under vibration — a common failure point in field-service equipment where intermittent contacts show up first. The press-fit termination option means you can assemble without solder, which helps if you're reworking a board or building a harness on site.
Press-fit and solder termination in a single part
The header supports both press-fit and solder termination — the press-fit tail lets you insert into plated through-holes without reflow, while the solder option gives a conventional joint. The brass contacts are rated for the full 2-position load.
