The Amphenol ICC BERGSTIK® II 92417-454HLF is a 54-position, dual-row, unshrouded male pin header on a standard 0.100" (2.54 mm) pitch with matching 0.100" row spacing.
Rated 5 A per contact at 110 V — the 5 A figure is per-circuit at the stated voltage, and the 0.100" pitch provides enough creepage for the 110 V rating without forcing an oversized board footprint. The overall contact length of 0.530" (13.46 mm) breaks down into a 0.320" (8.13 mm) mating length and a 0.110" (2.79 mm) solder-post length.
For higher mating cycle counts, a gold-plated variant in the BERGSTIK II series would be the appropriate choice.
