The Amphenol FCI BERGSTIK® II 86840-150HLF is a 50-position, dual-row, unshrouded male pin header on a standard 0.100" (2.54 mm) pitch grid. It's a right-angle through-hole board-to-board interconnect — the solder tails exit parallel to the PCB so the connector sits flush at the board edge, useful for mezzanine or perpendicular card mating where vertical space is tight. That plating grade — 30.0 µin — is the standard for repeated mating-cycle duty: it handles field servicing and board-level rework without the contact fretting you'd see on a thinner flash-gold or tin finish. The 5 A per contact is typical for signal-level board-to-board duty — GPIO, address lines, low-speed data buses — not a power rail, but the 0.100" pitch keeps enough copper cross-section for that current without thermal issues at the board footprint.
Board footprint and pinout
The mating pin length is 0.318" (8.08 mm), and the post length below the housing is 0.230" (5.84 mm). The insulator stands 0.190" (4.83 mm) off the board.
