What This Connector Is
The Amphenol 95687-166HLF is a dual-row, 66-position unshrouded male header in the BERGSTIK II series, designed for board-to-board stacking at 0.100 inch (2.54 mm) pitch. Through-hole solder termination and push-pull fastening make it a through-board retention style common in backplane and mezzanine card assemblies. All 66 circuits are loaded. The housing is black polyphthalamide rated UL94 V-0, and contacts are phosphor bronze with gold or Gold GXT plating at 30.0 µin (0.76 µm) on the mating face. Rated 5 A per contact at 110 V.
Plating Grade and Mating Duty
The 30.0 µin (0.76 µm) gold thickness on the mating face is at the upper end of the standard gold range — enough for multiple mate/unmate cycles without the contact degradation that tin-plated headers show after the first few reconnections. The push-pull fastening type means the header is not latched; retention depends on the receptacle housing's friction-lock or board alignment pins. For high-vibration environments, confirm the mating half carries a positive-lock feature.
