FCI 86503-424HLF BERGSTIK II Header, 24 Pos 2.54mm

The 0.100" (2.54mm) pitch and matching row spacing give it a standard footprint that routes cleanly on a two-layer board. Tin-on-tin mating surfaces with 100.0µin (2.54µm) thickness on the pin side — adequate for moderate mating cycles in a controlled environment, though gold would be the pick for frequent reconnects. Rated 5A per contact at 110V, this is a signal-density header — the 5A limit per pin is fine for logic-level power and I/O, but not for a bus rail. The through-hole solder tails (0.120" / 3.05mm post length) provide a solid mechanical anchor; the unshrouded design means no keying, so orientation and polarization depend entirely on the board layout and the mating receptacle's own features.
