Contact system and reconnect duty
The 77311-125-36LF is the 36-position single-row member of the BERGSTIK® unshrouded header line from Amphenol ICC (FCI). Mating contacts carry a gold or GXT™ finish at 30.0 µin (0.76 µm) thickness — the gold grade supports repeated mating cycles without exposing the phosphor bronze base metal.
Pitch and footprint fit
At 0.100" (2.54 mm) pitch, the 36 loaded positions occupy a 3.50" board edge — the same footprint pattern is shared across the BERGSTIK® single-row family, so a position-count change does not require a board layout revision.
