The Amphenol 86832-454HLF is a 54-position, dual-row unshrouded header from the BERGSTIK® II series, on the standard 0.100" (2.54 mm) pitch grid. It is a board-to-board interconnect — male pins, through-hole solder termination, push-pull fastening. The 54 circuits are fully loaded across two rows, with a row spacing of 0.100" (2.54 mm) matching the pin pitch. This is the high-position-count end of the BERGSTIK II line, meant for dense signal or moderate-power distribution on a standard PCB grid.
Rated 5 A per contact with tin-on-tin mating surfaces — the 100.0 µ" (2.54 µm) tin on the mating side is a heavy plating for moderate cycle life in a controlled indoor environment. The overall contact length of 0.525" (13.34 mm) breaks down as 0.325" (8.26 mm) mating length and 0.100" (2.54 mm) post length.
