The Amphenol BERGSTIK® II 93939-452HLF is a 52-position unshrouded male pin header on a 0.100" (2.54mm) pitch in two rows. It is a through-hole, right-angle board-to-board interconnect — the pins sit parallel to the PCB after soldering, which suits edge-of-board or mezzanine layouts where the connector must not stand upright. All 52 positions are loaded, so there are no unpopulated pins to track on the BOM. Tin is rated for the full 5A per contact, but it wears faster than gold under repeated mating cycles — this header is best suited for one-time or low-cycle-count connections where the board is assembled once and not reworked. The housing is rated UL94 V-0 and the insulation height sits at 0.190" (4.83mm) above the board surface. The right-angle post length is 0.120" (3.05mm) — standard for a 1.6mm-thick PCB.
