40-Way Rainbow IDC Ribbon Cable

This 40-conductor flat ribbon cable uses a 1.27 mm pitch and measures four metres in total length. It is intended for hobbyists and engineers building or repairing internal interconnects in consumer electronics and embedded systems. The rainbow colour coding simplifies pin identification during assembly or troubleshooting.

Thermals Noise and Power Draw

As a passive copper conductor the cable generates no heat, produces no audible noise and draws no power of its own. Signal integrity and any thermal load depend entirely on the connected circuitry and the current the designer chooses to run through each 1 mm diameter wire.

Pre-Split Conductors for Quick Termination

The individual conductors separate easily by hand, allowing direct insertion into standard IDC connectors, pin headers or crimp housings without stripping. This reduces assembly time on prototypes, ISP programmers, LCD panels, digital cameras and similar space-constrained devices.

Highlights

  • 40 conductors simplify multi-pin connections
  • 27 mm pitch matches standard IDC connectors
  • 4 m length allows flexible routing in builds
  • Flat ribbon separates cleanly for tidy terminations

Questions about this item

How do I separate the 40 conductors of the 1.27mm pitch ribbon cable without damaging them?

The 400cm flat ribbon cable is designed to separate easily; gently pull individual wires from the 40P bundle for clean terminations with standard connectors, jacks and pins.

Will the copper conductors of this 4m rainbow cable need replacement under normal use?

The copper wire conductors are solid-core and do not degrade with age; replacement is only required if the 1mm diameter wires are physically cut or the insulation is damaged.

What is the maximum continuous length I can run this 40P IDC cable before signal issues appear?

The supplied reel is 400cm long; for longer runs you must join additional sections, as signal integrity over extended distances depends on the specific application and termination quality.
