The 68023-409HLF is a 9-position, single-row unshrouded header from the FCI BERGSTIK® II series, on the standard 0.100" (2.54 mm) pitch. It is a board-to-board interconnect — a male pin header meant to mate with a matching receptacle or female header on a second PCB.
Rated 5 A per contact at 110 V, with tin plating on both the mating interface and the solder posts — the 100.0 µin (2.54 µm) tin finish is standard for cost-sensitive applications where mating cycles are limited and the environment is dry indoor. Housing is UL94 V-0 rated black thermoplastic.
This is a general-purpose board-to-board header for internal PCB interconnects — think control boards, I/O cards, or power distribution boards inside an enclosure.
