Internal USB 2.0 50cm IDC Cable

This 50 cm internal USB cable bridges motherboard 5-pin USB 2.0 headers to externally accessible USB 2.0 Type-A female ports. Built with a precision-moulded plastic IDC female connector and a robust USB A female receptacle, it delivers native USB 2.0 performance (up to 480 Mbps) without signal degradation. Conductors are colour-coded per USB specification: red (+5V), green (D+), white (D−), black (GND). Total length is 50 cm (19.6 inches), measured tip-to-tip, with ±1 mm manufacturing tolerance. Outer jacket is black PVC; contact pins are metal with anti-corrosion plating. Designed exclusively for internal use in desktop computers and embedded systems — not rated for external or hot-plug applications. Its mechanical design prioritises header retention strength and angular stability — the IDC connector’s wide contact area distributes insertion force evenly, preventing socket deformation common with narrow-pin alternatives. The cable’s bend radius is optimised for tight turns behind motherboards or around drive cages, and its consistent diameter allows uniform bundling with SATA or fan cables. No additional components — such as voltage regulators, ESD protection diodes, or signal repeaters — are included, keeping latency minimal and compatibility maximised. Target users include PC modders installing custom USB headers, technical trainers demonstrating motherboard I/O architecture, and industrial integrators embedding USB connectivity into control panels or instrumentation racks. Installation guidance is provided in the notes: always confirm pin 1 orientation first, press straight in without rocking, and avoid routing near high-heat zones like VRM heatsinks or GPU exhausts.
