The Amphenol 92417-428HLF is a 28-position, dual-row BergStik® II unshrouded header on the standard 0.100" (2.54mm) pitch grid. It's a through-hole, solder-terminated male pin header with a push-pull fastening style — the classic board-to-board interconnect for stacking or connecting parallel PCBs.
The 28 positions are fully loaded across two rows (2x14), with a row-to-row spacing of 0.100" (2.54mm) — same as the pitch. That means the footprint is a 0.100" x 0.100" square grid, which mates with any standard 0.100" IDC socket or BergStik receptacle. The overall contact length of 0.530" (13.46mm) breaks down as 0.320" (8.13mm) mating length and 0.110" (2.79mm) post length for the solder tail through the board.
