The Amphenol BERGSTIK II 87900-412HLF is a 12-position, dual-row unshrouded male header on a standard 0.100" (2.54 mm) pitch — the workhorse footprint for prototyping and production board-to-board interconnects.
The 0.720" (18.29 mm) mating pin length gives good reach through a standard 0.062" board into a mating receptacle — enough to clear a shrouded housing if the counterpart is a box header. The 0.100" row spacing matches the same pitch as the pin rows, so the footprint is a simple 2 x 6 grid of 0.025" square pins on 0.100" centers. Keep the keep-out zone clear of tall components on the solder side; the 0.120" post protrudes 3.05 mm below the board.
