The Amphenol 92634-158HLF is a 58-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board interconnect applications. It uses a 0.100" (2.54mm) pitch on both the mating interface and row spacing, matching the standard footprint for legacy and new designs alike. The right-angle through-hole orientation places the pin tails parallel to the PCB, suited for edge-mount or mezzanine-style stacking where the board-to-board axis runs parallel to the main board. Each square male pin is rated 5 A per contact, with a 110 V voltage rating. The mating contact finish is 30.0 µin (0.76 µm) gold over phosphor bronze — a plating grade that supports repeated mating cycles and resists corrosion in environments where tin would fret. The unshrouded design means the pins are exposed after mating, so the mating receptacle must provide the polarization and strain relief. The housing is rated UL94 V-0, a standard requirement for equipment inside an enclosure. All 58 positions are loaded; no optional empty positions to account for on the BOM.
Within the BERGSTIK® II family, the 92634-158HLF sits at the high-density end with 58 positions in two rows.
