RS PRO IDC Ribbon Cables

RS PRO range of flat ribbon cable which is suitable for use with all commonly available IDC connectors. This ribbon cable consists of parallel stranded tinned copper wire conductors laminated between layers of grey PVC film to form a flat ribbon cable suitable for use with Speedbloc® insulation displacement connectors. One edge has a red marker to indicate the first conductor. This flat cable can be split into any number of ways by tearing between conductors. The laminate ensures precise alignment and spacing between conductors, essential during assembly with the connectors. Each conductor is formed from 7 strands of 36 AWG (0.13 mm diameter), 28 AWG overall (0.08 mm2).
Flat ribbon cable consists of multiple individual small grade cable strands places parallel to each other to form a flattened single strip. This type of flat cable is found in electronic systems that need multiple data buses to link internal peripherals. Colour coding is often implemented in ribbon cables to minimise the risk of accidental reverse connections. Ribbon cable can also save space and time on circuit interconnecting assemblies.
