64-Position Dual-Row Unshrouded Header
The Amphenol ICC BERGSTIK® II 86503-464HLF is a 64-position, dual-row unshrouded header on a standard 0.100" (2.54 mm) pitch — the same pitch used across the BERGSTIK II family for board-to-board and wire-to-board interconnect. The square male pins are through-hole soldered, with a mating contact length of 0.250" (6.35 mm) and a post length of 0.120" (3.05 mm) for the PCB side. Rated 5 A per circuit at 110 V, with tin plating on both the mating surface and the solder post — the mating finish is a substantial 100.0 µin (2.54 µm), which gives this header decent corrosion resistance for general-purpose use without the cost of gold.
The 0.100" (2.54 mm) pitch is the classic 0.1-inch grid — it matches the vast installed base of ribbon-cable IDC connectors, BergStrip receptacles, and standard perfboard layouts. The 64 circuits mean this header fills a full 32-pin-per-row footprint; the dual-row layout with 0.100" row spacing keeps the board area manageable at about 1.6" long.
