36-Position Board-to-Board Header
The Amphenol BERGSTIK II 87901-136HLF is a 36-circuit, dual-row unshrouded male header on the standard 0.100" (2.54mm) pitch. It is a through-hole, push-pull solder-terminated board-to-board interconnect, with all 36 positions loaded.
The 0.100" pitch matches the legacy 2.54mm grid that most prototyping boards and standard IDC receptacles use. The unshrouded square pins (0.025" square, standard for this class) mate with any 0.100" pitch dual-row receptacle that accepts a 0.025" square post — no special keying or polarisation beyond the row geometry itself.
Board Layout Notes
The 0.820" (20.83mm) mating pin length gives plenty of reach through a standard receptacle body, and the 0.120" (3.05mm) solder post is short enough for single-sided boards but may need a longer post for thick backplanes.
