The Amphenol FCI 86840-426HLF is a 26-position, 2-row unshrouded header from the BERGSTIK II series, designed for board-to-board interconnects. It uses a 0.100" (2.54 mm) pitch on both the pin grid and row spacing, matching the legacy footprint common across many wire-wrap and IDC systems. Rated at 5 A per circuit with a 110 V voltage rating, the tin-on-tin contact system (100.0 µin on the mating side) is suited for low-cycle, cost-sensitive applications rather than high-reliability field-service connections.
At 26 positions, this header sits between the common 20-position and 34-position members of the BERGSTIK II series, all sharing the same 0.100" pitch and right-angle through-hole footprint.
