The Amphenol BERGSTIK® II 87052-438HLF is a 38-position, dual-row, unshrouded male pin header on a standard 0.100" (2.54mm) pitch. It's a board-to-board interconnect — through-hole solder termination, square pins, push-pull fastening. The 100.0µin (2.54µm) tin plating on the mating surface is sized for moderate-cycle signal duty; the tin-plated posts handle the solder-side connection. Rated 5 A per contact at 110 V, with a UL94 V-0 black insulation body.
The 0.100" pitch and 0.100" row spacing are the industry-standard 2.54 mm grid — the footprint matches a huge installed base of mating receptacles, including standard IDC sockets and crimp housings. The 100.0µin tin finish is adequate for 50–100 mating cycles in clean environments — if your application needs frequent reconnection or sees corrosive atmospheres, step up to a gold-plated variant in the same series.
