RFI/EMI Shielding

Knitwire Products knitted mesh provides a very effective and affordable solution to radio frequency interference (RFI) 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.

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 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.
