  • 40-pin female-to-female layout simplifies board-to-board wiring
  • 54 mm pitch matches standard header spacing for direct plug-in
  • 6 ft rainbow ribbon separates cleanly for tidy terminations
  • Rated -55 °C to +105 °C withstands harsh operating environments
  • Resists acid, alkalis, flame, moisture, oil, solvents and fungus

40-pin IDC ribbon cable for prototyping

This 40-way female-to-female flat ribbon cable uses a 2.54 mm pitch IDC connector. The 1.6 ft length suits breadboard work, ISP programming and internal board-to-board links in laptops, monitors or cameras. Each conductor separates cleanly for quick termination with standard pins or jacks.

Operating range and thermal behaviour

Rated from -55 °C to +105 °C, the cable withstands typical enclosure temperatures without degradation. The flat ribbon layout adds negligible resistance and produces no audible noise. Power draw is defined solely by the circuits it interconnects.

Chemical resistance and connector utility

The jacket resists acid, alkalis, flame, moisture, oil, solvents and fungus for long-term reliability. Female-to-female ends plug directly onto 40-pin headers, eliminating solder joints during development. Rainbow colour coding speeds wire identification in dense harnesses.

Questions about this item

How do I connect the 2.54mm pitch 40-pin IDC connectors without damaging the rainbow ribbon cable?

Align the red stripe on the cable with pin 1 on each header, press the female sockets straight onto the pins using even force, and avoid bending the flat cable sharply at the connector ends.

Will the cable insulation degrade if I route it near components that reach 105 °C?

The ribbon is rated from -55 °C to +105 °C; sustained exposure at the upper limit may eventually harden the insulation, so keep it away from continuous 105 °C surfaces.

At what current level will the flat ribbon cable become the thermal bottleneck during sustained use?

The 40 conductors share a compact 2.54 mm pitch, so heat builds up quickly; the cable itself will reach its temperature limit before the connectors do when multiple cores carry continuous current.
