9700 series EMI/RFI shielded mesh foil windows

EMI/RFI shielded mesh foil windows

For the highest possible EMI / RFI shielding performance, a woven electrically conductive microstructure of mesh is bonded between two layers of glass or plastic (stepped window). Alternatively, a single layer of Mesh foil 9000 series is fixed onto one side of a single glass or plastic window with self-adhesive (single window).

This can be done by laminating or edge bonding. The EMI-shielded mesh-foil windows can be provided with a silver bush bar, a electrical conductive gasket or can be supplied with a frame for easy mounting. Windows can optionally be provided with a water seal.


Light transmission

Opacity of mesh windows is 64,5%. A lack of available light should not be a concern, since an average pair of sunglasses allows less than 9% light to come through.


Applications

  • LCD displays;
  • membrane switches,
  • Touch screens
  • Defence / Avionics etc.
  • Devices for medical technology
  • For test and measuring instruments

Window types

EMI / RFI shielded mesh foil window types
Single window: Wire mesh fixed onto one side of a glass or plastic window Stepped window: Wire mesh bonded between two glass or plastic windows

Note that it is also possible to laminate the wire mesh under a custom angle to prevent moiré effect on for example monitors or LCD displays.


Window materials

EMI/RFI shielded mesh foil windows can be made from your existing windows or can be supplied as a new window made of:

  • polycarbonate (Material code P)
  • acrylic (Material code A)
  • glass (Material code G)

This applies both to single windows as for the stepped windows.

Please note : top layer can be affected by acid for example from the skin. To protect the conductive layer, you can apply a transparent film or use the adhesive side on top.

Small optical defects are allowed in this product. If you require a product that has absolutely no optical defect then contact us for the "superior selected quality". Please realize that by the extreme caution act in production these products can be several times more expensive.
