What this connector is
The Amphenol ICC 68695-156HLF is the 56-position member of the BERGSTIK II dual-row header series — a 0.100-inch (2.54 mm) pitch board-to-board header designed for right-angle through-hole mounting in industrial automation and communications equipment. All 56 positions are populated with square push-pull male pins terminated to 0.090 inch (2.29 mm) long solder leads, and the 0.100-inch row spacing matches standard 2.54 mm pitch routing grids so it drops into conventional board footprints without layout surprises. The contact finish at the mating interface is either gold or Gold GXT, applied at 30.0 µin (0.76 µm) over phosphor bronze — the thickness is the selection driver here, not the plating variant name. Current rating is 5 A per circuit at the contact, and the insulation body is rated UL94 V-0.
Board layout and stack height
Right-angle through-hole mounting places the body flush to the board surface with the mating face oriented parallel to the PCB plane — the 0.190 inch (4.83 mm) insulation height sets the standoffs above the board surface when the solder tails are seated. The push-pull square pins provide retention in the receiving receptacle without a locking latch; the connector is unshrouded, so polarisation relies on the housing keying of the mating half.
What drives the selection decision
56 positions is the key differentiator across the BERGSTIK II line — the 0.100-inch pitch, right-angle through-hole orientation, and 5 A per circuit rating are shared across the series. At 5 A per contact the circuit rating is sufficient for power-distribution use alongside signal duty, and the UL94 V-0 housing satisfies the flammability requirement for most industrial panel and DIN-rail equipment. Voltage rating is 110 V, which limits this to low-voltage internal board stacking rather than any line-voltage harness application. The gold or Gold GXT plating at 30.0 µin (0.76 µm) is a mid-to-premium plating grade — it supports multiple mating cycles better than standard tin and resists surface degradation in mildly corrosive environments. All 56 circuits are loaded, so there are no empty positions to account for in the footprint.
