Unique-Bargains 30 Pin Flat Rainbow Ribbon Cable 128cm 2.54mm Pitch

30-pin rainbow ribbon cable for internal wiring

This 30-pin flat rainbow ribbon cable measures 128 cm in length with a 2.54 mm pitch and 37.6 mm total width. It features female connectors at each end and is designed for internal wiring in office equipment, audio devices and video machines. The rainbow colour coding helps identify individual conductors during assembly or repair.

Practical limits of the 2.54 mm pitch interface

The 2.54 mm pitch suits standard IDC connectors but cannot carry high-current loads or high-speed differential signals over the full 128 cm run. Crosstalk between the 30 parallel conductors increases with length, so the cable is best kept to low-frequency control or data lines. The flat geometry also makes it vulnerable to repeated flexing near the connectors.

Installation notes and common issues

The female connectors press directly onto 2.54 mm pin headers without tools, but misalignment of even one pin can bend contacts or short adjacent lines. The 37.6 mm width may not fit between tightly spaced board components, so verify clearance before routing. Avoid sharp bends at the connector ends to prevent conductor fatigue.
