The Amphenol BERGSTIK® II 95687-450HLF is a 50-position, dual-row, unshrouded male pin header on the standard 0.100" (2.54mm) pitch. It is a board-to-board interconnect — the unshrouded design gives you access to the pins for probing or for stacking with a mating socket strip at the same pitch. The through-hole solder tails (0.360" post length) suit it for standard PCB thicknesses in a wave-solder assembly line.
Key ratings and what they mean for the fit
Rated 5 A per contact at 110 V — this is a signal-level header, not a power interconnect. The 0.100" pitch and dual-row layout give you 50 circuits in a 2.54 mm grid that aligns with standard perfboard and DIP footprints. The tin-on-tin contact finish (100.0 µin on the mating side, tin on the post) is a production-grade finish: it handles a moderate number of mating cycles in a controlled environment, but it is not specified for frequent field reconnection or corrosive atmospheres. The UL94 V-0 rated black housing meets the flame requirement for equipment inside an enclosure.
