What this header is
The Amphenol FCI (Amphenol ICC) 92634-464HLF is the 64-position member of the BERGSTIK II dual-row board-to-board header family, with a 0.100-inch (2.54 mm) pitch that matches the standard 0.100-inch grid used across a generation of industrial and telecom backplane architectures. Right-angle through-hole termination puts it in the stack-height-critical slot for mezzanine or parallel board-to-board stacking — the 0.190-inch insulation height tells you how much z-height the header occupies on the board face before the mated pair adds the receptacle standoff.
What the ratings mean for fit and duty
110 V is the voltage ceiling. That is well within safe limits for signal and low-level power on a board stack — the 0.100-inch row spacing and unshrouded design are the governing geometry here, not dielectric breakdown. Do not route high-line AC anywhere near this pitch without a creepage review. The push-pull fastening type is a friction-latch engagement — no tool needed, which is fine in the field but means you want to confirm your chassis has adequate support rails if vibration is present. The UL94 V-0 housing covers you in enclosed equipment where flame retardancy is a procurement or safety spec — common in industrial control cabinets and telecom infrastructure. The black housing is standard; colour is not a selection parameter but it confirms you are looking at the right variant in the bag packaging.
Sourcing and what to confirm before the BOM commit
The mating half is not specified in the listing — you need the matching dual-row 0.100-inch BERGSTIK II receptacle housing or IDC socket that accepts this header's pin geometry. Pull the Amphenol ICC BERGSTIK II datasheet to confirm the receptacle polarization and keying options before you specify the mating pair.
