Product Overview
The Amphenol 68405-166HLF is a 66-position unshrouded male pin header from the BERGSTIK® II series, designed for board-to-board interconnects. It uses a standard 0.100" (2.54 mm) pitch in a dual-row layout, with all positions loaded. The through-hole, right-angle mounting orients the pins parallel to the PCB, suiting board-edge or space-constrained layouts where the mating axis runs along the board surface. Rated 5 A per contact with a 110 V voltage rating, it handles signal-level and moderate power duty. The mating contacts carry 30.0 µin (0.76 µm) gold or Gold GXT™ plating, which provides corrosion resistance and supports repeated mating cycles in field-service or industrial environments.
Key Specs & What They Mean for Your Build
The 0.100" pitch is a de facto standard for prototyping and production boards — it matches the grid of most perfboards and the pad layout of many IDC receptacles. The 66 positions give you a high-density connection for parallel data or address buses, or for grouping multiple I/O signals into one connector. The right-angle orientation means the header sits flush against the board edge, so the mating receptacle plugs in parallel to the PCB — useful when vertical clearance is tight. The 30.0 µin gold on the mating surface is a robust plating grade: it handles hundreds of mating cycles without oxidation, making this header a good fit for modules that get swapped during testing or field maintenance. The UL94 V-0 housing is standard for equipment inside an enclosure where flame rating is required.
