Board-to-board breakaway header, 26 positions
The 77317-404-26LF is the 26-position member of Amphenol ICC's BERGSTIK® breakaway header line, a dual-row unshrouded board-to-board header with push-pull fastening. It mounts through-hole right-angle at 0.100" (2.54mm) pitch and mates with matching BERGSTIK receptacles. Tin-plated phosphor bronze contacts are rated 3 A per contact with a 78.7µin (2.00µm) tin finish on both mating and post surfaces.
Tin plating and breakaway design
The tin-on-tin contact system suits applications where mating cycles are moderate and cost per position is a factor. The breakaway construction allows snapping to a shorter length if fewer than 26 circuits are needed — the pitch and footprint are shared across the BERGSTIK series.
