The Molex 68031-136 is a 36-position, single-row unshrouded pin header from the BERGSTIK II series, on a standard 0.100" (2.54 mm) pitch. It is a board-to-board interconnect intended for through-hole soldering into a PCB, with a push-pull mating interface and no locking or shrouding features — the pins are exposed, so the mating receptacle or the board layout itself provides the alignment and retention.
All 36 positions are loaded, requiring a full 36-hole board layout.
This is an unshrouded male pin header — it mates with any standard 0.100" (2.54 mm) pitch female socket or receptacle housing that accepts 36 positions in a single row.
