What this connector is
The Amphenol FCI (now Amphenol) 68001-119HLF is a 19-position single-row unshrouded male pin header in the BERGSTIK II series, rated 3 A per circuit at 2.54 mm (0.100") pitch. Through-hole solder termination, gold-plated phosphor bronze contacts, UL94 V-0 black polyester housing, operating from -65°C to 125°C.
Board-to-board fit at 2.54 mm pitch
The 2.54 mm pitch drops into 0.100-inch grid layouts. The 0.450-inch overall contact length gives 0.230 inches of mating length, and the 0.100-inch insulation height sets the board-stack reference plane. The square post shape seats positively in matching square sockets or IDC insulation displacement receptacles in the same series. The 30.0 µin (0.76 µm) gold finish on the mating interface is the GXT-grade plating — thicker than standard flash gold — which extends reconnection cycle life in field-service scenarios. All 19 positions are populated, so the full 19-circuit bus or signal distribution path is live. The push-pull fastening type describes the insertion/dRetention feel; the header itself relies on the socket housing's latch for mechanical retention in the mated pair.
What it is used for
BERGSTIK II headers are the workhorse board-to-board vertical interconnect in industrial automation, instrumentation, and legacy communication equipment. The unshrouded design accepts matching friction-lock or latching receptacles in the same series; the single-row 19-circuit count fits multi-signal harnesses or daisy-chain bus topologies where circuit count and board footprint drive the choice. The -65°C to 125°C operating window covers both cold-start industrial environments and thermally elevated zones near power elements.
