40-way rainbow ribbon cable for Arduino

This 1 metre flat cable carries forty conductors on a 1.27 mm pitch and is intended for hobbyists and engineers wiring FC 40-pin IDC connectors. The rainbow colour coding makes individual wire identification straightforward during assembly and fault-finding. It suits digital cameras, camcorders, laptops, LCD panels and similar internal interconnects.

Behaviour across the full temperature range

Rated from minus 55 °C to plus 105 °C, the insulation remains flexible and retains its dielectric properties during prolonged exposure to heat or cold. The materials resist acid, alkalis, flame, moisture, oil and solvents, so the cable does not degrade when routed near power components or in harsh enclosures. Conductors separate cleanly for repeated re-termination without fraying.

Practical limits of the 1.27 mm pitch interface

The 50 mm overall width fits standard 40-pin IDC sockets but leaves no margin for wider connectors or higher-density pinouts. At 1 metre the cable is suited to board-to-board links inside a chassis rather than long external runs where crosstalk or voltage drop could become significant. Builders needing more than forty conductors or a finer pitch must choose a different cable.

Questions about this item

Does the 1.27 mm pitch cable stay flexible after hours at 105 °C?

The ribbon is rated from -55 °C to +105 °C and resists flame, oil and solvents, so it remains pliable during extended high-temperature operation.

Which connectors or pins must I already have to terminate the 40 conductors?

You need standard 40-pin IDC connectors or individual wire pins that match the 1.27 mm pitch; the conductors separate cleanly for those terminations.

Will the 50 mm wide rainbow cable fit alongside older 1.27 mm pitch ribbons in the same chassis?

Yes — it shares the same 1.27 mm pitch and 50 mm total width, so it stacks neatly with legacy flat ribbons using that spacing.
