Connector identity and board fit
The 1-178297-5: This is a single-row, 8-position header from the Dynamic D-3100 series, with a 3.81mm mating pitch. It is a shrouded 4-wall header with a detent lock, designed for board-to-board or cable connections.
The 250V voltage rating and 3.81mm pitch are typical for signal-level industrial interconnects. The tin-plated mating surface (78.7µin thick) handles moderate mating cycles — expect a few hundred mates before wear becomes visible. The board lock feature holds the header in place during wave soldering and resists vibration after assembly.
