Electromagnetic compatibility (EMC) is the property of the cable which prevents it from causing electromagnetic interference and/or being affected by electromagnetic fields.

Background: Whenever supply lines, sensor and control cables are in close proximity to one another – in tight cable drag chains or thick cable bundles – electromagnetic fields are generated that are typical for automation and machine construction. Occasionally assemblies and hybrid cables can be quite a headache for engineers. Electromagnetic fields can cause noise that leads to severe signal degradation or even unwanted signals.
