BERGSTIK® II Unshrouded Header – 54 Positions, 0.100" Pitch
The Amphenol BERGSTIK® II 86503-454HLF is a 54-position, dual-row, unshrouded male pin header on a 0.100" (2.54 mm) pitch. It is a board-to-board interconnect, through-hole soldered, with a push-pull fastening system and no shrouding — the pins are exposed for direct mating with a matching receptacle. The 54 loaded positions match the full circuit count, so every pin carries a signal or power path.
The 0.100" (2.54 mm) insulation height means the mated stack height with a matching receptacle is around 0.200" (5.08 mm) plus the receptacle's own height — check the receptacle's mating dimension for the exact z-height budget.
