The Amphenol FCI 91276-126HLF is a 26-position unshrouded male pin header from the BERGSTIK® II series, on a standard 0.100" (2.54 mm) pitch. The single-row layout and unshrouded design keep the board footprint compact — useful when the mating receptacle is on a parallel board and the header sits at the edge of the PCB. Contacts are phosphor bronze with a gold or Gold, GXT™ finish on the mating surface, 30.0 µin (0.76 µm) thick — enough gold for repeated mating cycles in a clean environment without risking contact fretting. The 5 A per-contact rating at 110 V is typical for a 0.100" pitch header; the limiting factor is the pin density and the temperature rise through the housing, not the contact itself. The 0.900" (22.86 mm) mating pin length gives good wipe before the contact beams engage — useful when the mating receptacle has a deep cavity.
The 0.100" (2.54 mm) pitch matches the common 0.100" header pattern, so it drops into a standard perfboard or a custom PCB layout without a footprint change.
