Board-to-board breakaway header
The 95278-802-40LF is the 40-position member of Amphenol ICC (FCI)'s BERGSTIK breakaway header line, a dual-row unshrouded board-to-board header with a 0.100" (2.54 mm) pitch and 0.100" (2.54 mm) row spacing. Gold GXT plating on the mating contacts and a UL94 V-0 thermoplastic housing support the 3 A per-contact rating across the -65°C to 125°C operating range.
BERGSTIK series fit
The 95278 base number identifies this as a BERGSTIK breakaway header — the unshrouded push-pull fastening and 0.315" (8.00 mm) mating pin length are consistent across the series, so the board footprint and mating receptacle selection carry across sibling position counts.
