In the industrial sector, EMC plays a particularly key role because complex machines and systems are extremely susceptible to electromagnetic interference. Such undesired EMC effects, however, can be counteracted with the effective shielding of all components. On the one hand, good shielding reduces the amount of interference emitted by an electrical apparatus while at the same time reducing its susceptibility to impaired performance due to electromagnetic effects.

Not only cables themselves but also all other components that are part of the installation must provide shielding characteristics. Cable glands thus become active components and must ensure that the quality of the shielding at sensitive interconnection points remains intact and that there are no losses in shielding attenuation. For this reason, it’s necessary to not only use a maximally shielded cable but also add EMC-compliant cable glands. Although there is no separate EMC standard for these components, they play a large contribution towards making it possible to meet the EMC characteristics prescribed by manufacturers.
