The FCI Amphenol 87052-126HLF is a 26-position, dual-row unshrouded header in the BERGSTIK® II series, built for board-to-board and wire-to-board signal interconnects where a standard 0.100" (2.54 mm) pitch and through-hole solder termination are the baseline. All 26 positions are loaded with square male pins in phosphor bronze, finished with 30.0 µin (0.76 µm) gold or Gold, GXT™ on the mating surface — a plating grade that supports repeated mating cycles without contact fretting in moderate industrial or telecom environments.
The 0.100" pitch and 0.100" row spacing match a standard 0.100" x 0.100" grid footprint, so board layout tools and protoboards accept it without custom pad patterns.
No crimp tooling needed; this is a board-mount component, so the assembly step is solder only.
