What this connector is
The Amphenol ICC 87185-110HLF is the 10-circuit member of the BERGSTIK II single-row header series, configured for board-to-board stacking at the standard 0.100-inch (2.54 mm) grid. It carries a 5 A per-circuit current rating with 30 µin (0.76 µm) gold plating over phosphor bronze contacts — a higher durability finish than the tin plating found on lower-cycle members of the same family. The push-pull fastening type means it mates with a corresponding friction-lock receptacle; the unshrouded header leaves the sides open, so the mating half's housing must provide the lateral keying and guide walls.
Key ratings and what they mean
Pitch is the board footprint driver: 0.100" (2.54 mm) mates with the entire BERGSTIK II and competing 2.54 mm pitch strip ecosystem, but the 10-position count must match the circuit count on the BOM line — adding or removing positions means switching to a different base part number in the same series. Contact plating grade governs reconnection duty: the 30 µin (0.76 µm) gold finish supports significantly more mate/unmate cycles than tin-plated variants, making this better suited to field-service or test-fixture applications where the connector is cycled repeatedly. The 110 V rating is the voltage ceiling; it sits comfortably below the dielectric withstanding potential of the polyester housing and limits this header to low-voltage signal and control circuits rather than power distribution. The UL94 V-0 flammability rating is the compliance checkpoint for industrial control panels and appliance modules where flame retardance is a procurement requirement. Insulation height is 0.100" (2.54 mm) — this is a standard-profile header, not a low-profile or high-stacking variant; the mated stack height when used in a mezzanine pair is determined by the board thickness and any intermediate spacing, not by a defined guide datum on the header itself.
