The Amphenol ICC 87901-134HLF is a 34-position, dual-row BERGSTIK® II unshrouded header — a through-hole, board-to-board interconnect built on the standard 0.100" (2.54 mm) pitch. It carries all 34 positions loaded with square male pins in phosphor bronze, finished with 30.0 µin (0.76 µm) of gold or GXT™ on the mating surface. This is a general-purpose pin header for prototyping, production board stacking, or any application needing a reliable, low-cost separable interface between PCBs.
The 0.820" (20.83 mm) mating pin length gives clearance for stacking with standard receptacles, while the 0.120" (3.05 mm) solder post length suits typical 0.062" to 0.093" PCBs.
