The Amphenol FCI 68405-126HLF is a 26-circuit, dual-row male header from the BERGSTIK® II series, on the standard 0.100" (2.54 mm) pitch that defines the board-level footprint for this class of interconnect.
The 0.100" pitch and 0.100" row spacing are the industry-standard 0.025" square-pin grid — the same footprint used by legacy BergStik, Samtec, and many generic 2.54 mm headers. The 26 positions are fully loaded (all positions populated), so the BOM count matches the physical pin count.
