Single-row unshrouded header
The 77311-402-09LF is the 9-position member of Amphenol's BERGSTIK unshrouded header line, configured as a single-row board-to-board interconnect. It carries tin-plated mating contacts rated 3 A per contact, through-hole solder termination, and a 0.100" (2.54 mm) pitch that matches standard breadboard and prototype grids.
Board-fit and housing details
Unshrouded push-pull fastening keeps the mating interface accessible for manual insertion and extraction; the single-row layout leaves adjacent board space open for routing. The thermoplastic housing carries a UL94 V-0 flammability rating and operates from -65°C to 125°C.
