The Amphenol BERGSTIK II 68695-140HLF is a 40-position, dual-row, unshrouded male pin header on a 0.100" (2.54 mm) square grid — 0.100" pitch and 0.100" row spacing. All 40 positions are loaded with square phosphor bronze pins, and the mating surface carries 30.0 µin (0.76 µm) of gold or GXT plating — a robust signal-grade finish that handles repeated mating cycles and resists corrosion in moderate industrial environments. The push-pull fastening and unshrouded profile mean it mates with standard BERGSTIK II receptacle strips and fits into tight board-edge layouts where a shroud would block access.
The decision comes down to circuit count: 40 positions vs 30, with the same footprint per position. If the BOM calls for 30 signal lines, the 30-position part saves board space and cost; if the design needs the full 40, this header loads them all.
