What this connector is
The Amphenol FCI BERGSTIK II 86832-470HLF is a dual-row, 70-position male header in the 0.100-inch (2.54 mm) pitch board-to-board family. All 70 circuits are loaded — it ships as a full-position connector, not a cut-to-length strip. The push-pull fastening type means the header relies on a friction-fit engagement with the matching receptacle; there is no screw-lock or latch to resist pull-out under vibration, so this is a better fit for stable equipment interiors than for shock-prone environments. Contact material is phosphor bronze with tin plating on both the mating face and the solder tail, at 100 microinches (2.54 micrometres) thickness on the mating side. That plating grade is characteristic of permanent-mount board-to-board interconnects — sufficient for the initial mate resistance and solder joint integrity a through-hole header needs, but not a hard-gold finish intended for repeated mating cycles. The unshrouded pin geometry means there is no polarization keying on the header itself; alignment and polarity protection must come from the receptacle housing or the board layout.
Ratings and what they mean for the build
Rated 5 A per circuit at 110 V. At 0.100-inch pitch the current per contact is not the constraint — the circuit count and the board routing density are. Five amps per circuit is adequate for low-level power distribution at the board level (sensor rails, indicator logic, low-current actuator drive), but it is not a power-delivery bus bar. If the design intent is to run higher currents through multiple parallel contacts, check the derating curve against the operating temperature — the header's UL94 V-0 rated housing limits the thermal ceiling relative to free-air terminations. The insulator stands 0.100 inch (2.54 mm) off the board surface, giving a 13.34 mm overall contact length with 8.26 mm of engagement length when mated. That geometry defines the mated stack height contribution for any mezzanine or stacked board assembly — the 0.100-inch insulator stand-off is the board-to-board z-height budget increment that the layout engineer must carry. The dual-beam contact geometry (square pin shape, through-hole solder tail) provides mechanical retention in the PCB hole but does not imply a sealed interface — no O-ring or gasket surface is present. The housing is rated UL94 V-0, which covers the flammability requirement for enclosed consumer, industrial, and telecom equipment. No IP sealing rating is listed — the connector is not designed for washdown or outdoor exposure without an intervening sealed enclosure or gasket interface on the mated pair.
