RFI/EMI Shielding Solutions
Knitwire Products knitted mesh provides a very effective and affordable solution to RFI/EMI shielding.
All electronic equipment sensitive to electromagnetic interference (EMI) must be shielded from external interference sources. In addition to this, any equipment which produces electromagnetic radiation, must be isolated to prevent any degradation to the performance of surrounding electrical and electronic equipment.
Knitted wire mesh provides a perfect solution for many applications in terms of RFI/EMI Shielding, especially where it is necessary to bridge gaps and leakage points in electronic enclosures.
Copper RFI/EMI Shielding
Our most recently developed copper foil is a favourite within the RFI/EMI shielding industry. Our copper knitted wire mesh sleeve offers protection for the copper foil, making it more robust and prolonging the life of the overall product.
The copper foil and mesh is ideal for outdoor areas due to its anti-corrosive properties, and has a working temperature range of -40°C to 149°C. The foil and mesh combination can easily be wrapped around wires and cables. Our foil and tape combination is extremely lightweight, flexible and easy to use.
You can either purchase the copper foil itself or we can offer an adhesive to enable you to stick the product onto surfaces rather than tying them around.
We supply these in a width of 45mm and to any length required.
Strips and cores can be produced in many different cross sectional forms with or without ‘fins’ for mounting into extrusions. The outer layer(s) of wire mesh provide an excellent shielding whilst the elastomer or mesh core provides a high level of resiliency.
Compressed gaskets can be produced from knitted wire mesh to make ideal grounding of RFI/EMI shielding around shafts.
Cable wrap mesh is supplied in a continuous, flattened stocking, two-ply tape for shielding around cables and loom assemblies. By overlapping the wraps, 4 layers of mesh provide an excellent shield.
Any commercially available wire can be used although the most popular materials are monel and stainless steel, followed by tinned copper clad steel and aluminium. Tinned copper clad steel provides a very good magnetic corrosion resistance whereas monel offers very good shielding performance and corrosion resistance. Monel has a hig tensile strength and is most commonly used in aluminium enclosures.
