Board-to-Board Header for General-Purpose Interconnects
The Amphenol 91276-125HLF is a 25-position, single-row unshrouded male pin header from the BERGSTIK II series, on the standard 0.100" (2.54mm) pitch.
The 30.0 µin (0.76 µm) gold plating on the mating surface is what governs the real duty here — it supports repeated mating cycles without contact fretting, making it a solid choice for field-service or test applications where the connector sees more than a few insertions. The 0.100" (2.54mm) pitch matches the standard breadboard and perfboard grid, so the footprint fits common prototyping layouts.
