The Amphenol FCI 91276-122HLF is a 22-position unshrouded male header from the BERGSTIK® II series, on 0.100" (2.54 mm) pitch. The 5 A per-circuit rating at 110 V puts this squarely in signal-duty territory, though the 30.0 µin gold or GXT™ plating on the mating surface gives it the cycle life for repeated connect/disconnect in test or programming jigs.
The unshrouded design means there is no keying or polarization — it mates with any compatible 0.100" pitch female header or socket strip that accepts a 0.025" square pin. The 0.900" (22.86 mm) mating pin length gives good wipe before full engagement, useful for blind-mate or stacked board pairs where the connector halves are not perfectly aligned at first contact.
