The 0.100" (2.54mm) pitch on both rows and between rows matches the standard 0.100"-pitch ribbon cable grid — the same footprint used across decades of parallel data buses, printer interfaces, and internal board-to-cable links. The gray housing carries a polarizing key and a feed-through feature — the key prevents mating with a non-keyed header, and the feed-through allows the cable to pass through a panel cutout while the connector body sits on the far side. Gold plating on the female sockets, at 31.5µin (0.80µm), gives a robust mating surface for repeated connect-disconnect cycles in field service or test fixtures.
Wire Sizing and Termination Reality
This IDC receptacle accepts 28 AWG stranded wire and 26-30 AWG solid wire — the stranded 28 AWG is the most common ribbon cable gauge for signal-level interconnects. The connector is designed for ribbon cable only, not discrete wires.
