The Amphenol 68405-220HLF is a 20-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board interconnects on the standard 0.100" (2.54mm) pitch grid. It carries male square pins with gold or GXT™ plating on the mating surface — 15.0µin (0.38µm) thick — rated for 5A per contact at 110V.
The 0.100" (2.54mm) pitch is the legacy industry standard — any board laid out for a 0.100" header grid accepts this part. The 20 positions, all loaded, match the BOM line for a 20-circuit interconnect. Being unshrouded, there is no polarization keying: the mating receptacle must be oriented correctly by the board layout, not by the connector shell.
