The Amphenol FCI 87052-466HLF is a 66-position (2×33) unshrouded male header in the BERGSTIK II series, on a standard 0.100" (2.54 mm) pitch with the same 0.100" row spacing. The 0.100" insulation height and 0.770" mating pin length give a generous entry window for the receptacle — the overall contact length of 0.990" means the solder tail protrudes 0.120" below the board. With all 66 positions loaded and tin-plated phosphor bronze contacts, this is a signal-density header for through-hole soldering into a dual-row footprint.
Plating and Duty Cycle
The tin on the solder post matches the mating finish, so the entire current path is tin-to-tin once soldered.
Compliance and Housing
RoHS compliance is typical for this series, though the specific directive status should be confirmed against the factory lot code.
