7910-Conductive O-rings

Conductive O-rings 7910

For EMI shielding applications in grooves. Also suitbale where IP seal is required.

The 7910 series Jointed O-ring are practically the same as the 7900 series O-Profiles, however, this is a turnkey closed O-ring. They are used where environmental and EMI screening is required but were little space is available.

Four kinds of cores are available:

  • solid
  • hollow extrusion
  • cell rubber
  • small rectangular shapes

These cores can be covered with metallized fabric foils or made out of conductive rubber. For optimal shielding performance a compression of 5-10% is recommended for solid elastomers and 10-50% for hollow extrusions and cell rubbers.
