EMC cable entry systems
Solutions for conducted and field-bound disturbances
In case of conducted as well as field bound EMI disturbances, our split cable entry system EMC-KEL-DS and our split cable gland EMC-KVT-DS offer an effective way to divert and block those disturbances and provide an alternative to conventional EMC cable glands – especially when routing cables with connectors.

Today’s industrial process technology is far more sensitive to electromagnetic disturbances creating the need for proper electromagnetic compatibility.
But what does that mean?
This video explains clearly why EMC is so important.
The industrial process technology demands increasing security against disturbances for electrical MCR facilities (measure, control, regulate). Special emphasis is being placed on the derivation of electromagnetic interference. A distinction is made between conductive and field-bound disturbances.
A large contact area of the cable shield for the derivation of the interference to a conductive enclosure wall combined with the shielding of the enclosure interior, generally offers a good solution for both types of interference.
The cable entry frames EMC-KEL-DS, EMC-KEL-U and EMC-KEL-E are based on the icotek products KEL-U and KEL-E. Due to a conductive surface, interferences in the cable shields on the control cabinet can be easily dissipated. Field bound disturbances are derived by the metallisation. Between the EMC-KEL and the metal wall a conductive flat gasket (included) is mounted.
The cable grommets type EMC-KT are made of a very conductive elastomer. Thus, interferences are dissipated from the cable shield directly via the grommet, the frame and the flat gasket.
This ensures full-area protection against field-bound interference!
Easy assembly of the EMC cable entry frames
Easy assembly of the EMC cable entry frames
The EMC cable entry frames are mounted via screws. The cable entry frames are available in various sizes and are based on standard cut-outs of multi-pin heavy industrial connectors.

The split EMC cable gland
The split EMC cable gland EMC-KVT-DS is based on the standard icotek KVT product. However, the EMC-KVT-DS has been metallised (galvanise coated) to create a conductive surface.
The opened, conductive EMC cable gland is fitted with two grommets, an EMC-KT grommet for contacting the cable shield and a regular KT grommet for sealing according to IP55 and for strain relief of the cable. Earthing is achieved with the EMC locknut.
Test Results
Field-bound disturbances
Regarding the field-bound disturbances and depending on the application, in the relevant frequency ranges up to 3 GHz constant measurements of at least 34 dB have been achieved. Below the attenuation range, the curve falls only at extreme high frequencies above 3 GHz.
Conducted disturbances
The EMC-KEL shows during cable-bound disruptions stable attenuation values up to 40 dB in the frequency ranges from 9 kHz to 30 MHz.
