The Amphenol BERGSTIK II 95687-166HLF is a 66-position dual-row unshrouded male header on the standard 0.100-inch (2.54 mm) pitch. It is a through-hole solder-terminated board-to-board interconnect, designed for applications where a reliable, low-profile pin header is needed to mate with a matching receptacle. The 66 circuits are fully loaded across two rows, giving you a dense but routable pin field for parallel board stacking or wire-to-board harnesses. Rated 5 A per contact at 110 V, this header handles signal and moderate power duty. The 30.0 µin gold plating on the mating interface — either gold or Gold, GXT™ — gives it a solid mating cycle life for field-serviceable connections, well above what a tin-plated part would tolerate in repeated mate/unmate scenarios. The housing is black PA polyphthalamide rated UL94 V-0, so it meets the flame-retardancy requirement for equipment inside an enclosure. The push-pull fastening means it relies on the friction of the pin field for retention — no latch, no lock — which is standard for unshrouded headers in board-to-board or cable-to-board applications where the mating half has its own retention.
Mating and termination
This header mates with any standard 0.100-inch pitch dual-row receptacle — typically a BergStik or equivalent female socket strip. The 0.360-inch (9.14 mm) mating pin length gives enough engagement depth for a secure connection with most socket connectors. The through-hole solder tails are 0.360-inch long, suited for standard PCB thicknesses in the 0.062-inch to 0.093-inch range. The overall contact length of 0.820-inch (20.83 mm) includes the full pin from the mating interface to the solder tail tip.
