EMC-Protection

Electromagnetic Compatibility (EMC)

 
EMC protection (electromagnetic compatibility) refers to methods for reducing or shielding electromagnetic interference in order to ensure the proper functioning of electronic devices. This includes, for example, special enclosures, filters or earthing concepts that prevent interference from entering or leaving the device.

EMC optimization of plastic enclosures

Depending on your requirements, we offer two methods for EMC optimization of plastic enclosures:

  • Coating with copper conductive paint
  • Aluminum evaporation

 
For both processes, an electrically conductive coating is applied to the inside of the enclosure. In addition, we install a metallically coated HF seal to create a circumferential contact and thus seamless shielding between the enclosure cover and base. The mechanical properties of the plastic are not changed by the coating.

EMC optimization of aluminium enclosures

Due to the electrically conductive base material, aluminium enclosures offer a significantly better basic shielding than plastic enclosures without additional adjustments. For further optimisation, we keep the seal contour (tongue and groove) completely free of paint. In addition, we install a conductive HF sealing to create a circumferential contact and thus a seamless shielding between the enclosure cover and base part.

EMC optimization through accessories & components

To complete the EMC measures, we offer appropriate EMC cable glands in various materials for cable entry. These have a connection possibility of the cable shield to the enclosure ground connection.
 
The possibilities of EMC optimisation are not limited to the enclosure itself. A significant increase in shielding performance can be achieved by using components or assemblies that are insensitive to electromagnetic interference.

Please note

The verification and confirmation of immunity to interference and sufficiently low emitted interference are regulated by EMC directives. Separate verification must always be provided by an independent laboratory and is the responsibility of our customers.
