The Amphenol 68705-434HLF is a 34-position, single-row BERGSTIK® II unshrouded pin header, designed for board-to-board interconnect applications where a simple, low-cost, and reliable solder connection is needed. The header carries tin-plated phosphor bronze contacts rated at 5 A per circuit, with a thick 100.0µin (2.54µm) tin finish on the mating surface — good for cost-sensitive designs where the connector is mated infrequently or permanently soldered.
The 0.100" (2.54mm) pitch is the dominant dimension for board layout — it sets the pad spacing and determines whether the header fits a standard 0.1" grid. The 34 positions are all loaded, so every pin is present; there are no unpopulated positions to confuse assembly or BOM matching.
This is a through-hole solder-terminated header. The 0.200" (5.08mm) mating pin length provides a solid insertion depth into a standard receptacle, while the 0.095" (2.41mm) post length is sized for a typical 0.062" (1.57mm) PCB. The unshrouded design means it mates with any matching 0.100" pitch female socket header or IDC receptacle — no shroud alignment needed.
