The Amphenol ICC (FCI) BERGSTIK® 75844-150-34LF is a 34-position, dual-row unshrouded male pin header on a standard 0.100" (2.54mm) pitch. This is a through-hole solder-terminated, push-pull (unlatching) header suited for board-to-board or cable-to-board interconnect in industrial control, test equipment, and general-purpose PCB stacking.
The 0.100" (2.54mm) pitch is the de facto standard for prototyping and general-purpose PCBs — it matches the footprint of most breadboards and perforated boards, and the 0.100" row spacing keeps routing density predictable. The 0.230" (5.84mm) mating length gives a solid wipe on the receptacle contact, and the 0.123" (3.12mm) post length is standard for a 1.6mm PCB.
