The 86840-148HLF is a 48-position member of the BERGSTIK II series from Amphenol FCI — a 2-row unshrouded male header on the standard 0.100" (2.54 mm) pitch, loaded all positions. It's a board-to-board interconnect, through-hole mounted at a right angle, so the pins sit parallel to the PCB plane. That orientation suits board-edge mezzanine or daughtercard applications where the mating axis runs along the board rather than perpendicular to it. The 5 A per-contact rating holds at 25°C; above that, derate per the standard curve. The 110 V rating and UL94 V-0 black housing cover the typical signal-level duty inside a grounded enclosure.
Unshrouded, push-pull fastening — mates with any standard 2-row 0.100" pitch receptacle that accepts 0.025" square pins. The right-angle tail is 0.230" (5.84 mm) long, which fits a standard through-hole footprint with no special drill depth. For a dense 48-position layout, the 2.54 mm row spacing keeps routing manageable on a 2-layer board.
