The Amphenol BERGSTIK II 87901-150HLF is a 50-position, dual-row unshrouded male pin header with 0.100" (2.54 mm) pitch, designed for board-to-board stacking in industrial and instrumentation applications. The housing is black thermoplastic rated UL94 V-0, and all 50 positions are fully loaded. Contacts are phosphor bronze with 30.0 µin (0.76 µm) gold or Gold GXT™ plating on the mating face, rated 5 A per circuit at the listed voltage. The push-pull fastening and square pin cross-section suit the matching IDC or machine-wrap receptacle in the same series. Termination is through-hole solder with a post length of 0.120" (3.05 mm) and overall contact length of 1.040" (26.42 mm), giving adequate lead-in for wave or hand-solder assembly.
The 50-position BERGSTIK II header uses 0.100" pitch and a dual-row layout standard across the series — position count is the primary differentiator for BOM alignment. No peer variant in the same series with a meaningful circuit-count or rating delta is documented here.
