Product Description

An EMC shielding gasket is simply a connector of two opposing metallic surfaces which makes them appear electrically as one continuous RF absorber. Nearly every area of the electronic marketplace may require some form of electronic shielding. Primary uses commonly include:
  • RF gaskets
  • Grounding
  • Electrostatic discharge
  • EMI/RFI shielding for emissions and immunity
  • High strength copper alloys, and in particular Beryllium Copper, meets the tougher, more demanding specifications
