What this connector is
The Amphenol FCI BERGSTIK II 86832-112HLF is a 12-position dual-row 0.100 inch (2.54 mm) pitch board-to-board header with male square pins designed for through-hole solder mounting. Phosphor bronze contacts carry 5 A per circuit at up to 110 V, with 30.0 µin (0.76 µm) gold plating on the mating interface. The unshrouded push-pull body accepts the matching IDC receptacle housing from the same series and sits in a black UL94 V-0 insulated housing rated to 110 V.
Pinout and board layout
With 0.100 inch row spacing and 0.100 inch post length, the 2-row layout gives a 12-position footprint in a rectangular array. The 0.525 inch overall contact length includes an 0.325 inch mating section — the pin extends enough to reach the receptacle spring while keeping the board-side shoulder close to the surface for low-profile stacking. The 0.100 inch insulation height matches the pitch, so the housing sits flush with the board surface when wave-soldered. Because the header is unshrouded, polarisation relies on the receptacle keying slot — confirm the housing polarity feature before layout.
