The Amphenol FCI 86832-134HLF is the 34-circuit member of the BERGSTIK II unshrouded header series — a dual-row board-to-board stacking header rated 5 A per circuit at 110 V with gold-plated phosphor bronze contacts. With 34 positions across two rows at 0.100-inch (2.54 mm) pitch, all circuits are loaded. The push-pull fastening type holds the header in the mated condition without a separate locking clip — suited for applications where the board stack is finalized at assembly and not routinely separated. Contact finish is gold or Gold GXT at 30.0 µin (0.76 µm) on the mating interface, with a square pin contact shape and 0.325-inch (8.26 mm) mating length per contact. Overall pin protrusion is 0.525 inch (13.34 mm) from the shoulder, with 0.100 inch (2.54 mm) extending past the board side — standard for dual-row 0.100-inch pitch headers that mate into matching shrouded or unshrouded receptacles in the BERGSTIK II family.
Insulation body is black polyamide (UL94 V-0 rated) with an insulation height of 0.100 inch (2.54 mm) — the same as the contact row spacing, giving a uniform board footprint with no standoff step. Contact material is phosphor bronze. The unshrouded header design accepts any compatible BERGSTIK II receptacle of matching position count and row spacing — the 0.100-inch (2.54 mm) dual-row pitch is the governing interoperability standard across the series. Polarization against mis-mate is handled by the receptacle shroud or keying feature on the mating half, not by the header itself.
Termination is through-hole solder (0.100-inch grid-compatible with standard SMT reflow or hand-solder profiles). The 5 A per-circuit rating is de-rated from the contact material ceiling — at 5 A per contact with all 34 circuits carrying current simultaneously, thermal rise stays within the UL94 V-0 housing envelope for typical board-level stack conditions.
