Colour coding rings are coloured rings – available individually or in packs of assorted colours – that help separate and identify certain cables using colour. Typically attached or integrated into the connector that terminates a cable, they reduce wiring system complexity and the chances of wiring errors by grouping and categorising different types of cables.
Colour coding rings are essential when using a multitude of cable runs. Cables are often run through channels and walls to reduce the required cable length, protect them and to remove trip hazards. However, this can make them difficult to trace and identify after installation. Colour coding can be useful in identifying each different cable run.
Colour coding rings are used in a diverse range of applications to provide easy visual identification. They are suitable for use, for example, in audio applications such as for identifying phono connectors, or in an industrial context with rugged circular connectors at a wiring panel.
