The Amphenol BERGSTIK 75844-150-40LF is a 40-position, dual-row unshrouded breakaway header on the standard 0.100" (2.54mm) pitch. It serves as a board-to-board or wire-to-board interconnect, typically mated with a matching receptacle or IDC socket. Rated at 5A per circuit at 110V, with gold GXT™ contact plating at 30.0µin (0.76µm) on the mating surface, it's built for repeated mating cycles and corrosive environments. The through-hole solder termination and UL94 V-0 black thermoplastic housing suit it for enclosed equipment requiring flame-rated components, with an operating range of -65°C to 130°C.
The 0.100" (2.54mm) pitch is the de facto standard for this class of header — it matches the footprint of legacy ribbon-cable IDC connectors and most through-hole prototyping grids. The 0.230" (5.84mm) mating pin length gives enough engagement depth for standard receptacle housings.
