The Amphenol FCI 68031-122HLF is a BERGSTIK® II single-row, unshrouded male pin header with 22 positions on a 0.100" (2.54 mm) pitch. The black housing is rated UL94 V-0. This is the 22-position member of the BERGSTIK II series, loaded in all positions.
The 0.100" (2.54 mm) pitch is the standard breadboard-compatible spacing — it matches the vast installed base of 0.100" receptacles and perfboard layouts. Overall contact length is 0.513" (13.03 mm), with a 0.183" (4.65 mm) solder tail for through-hole boards. Unshrouded push-pull fastening means this header is a bare pin strip — no polarization or keying. The board layout must provide the alignment; the mating receptacle's housing supplies the polarization.
