EMI shielding knitted wire mesh can be used as economical gaskets for EMI/RFI shielding. All knitted mesh configurations come on spools, coils or are cut to length as individual gaskets with or without end seals. Standard profiles for a wide variety of applications include round, round with tail, double round with tail, half round (D) and rectangular. Most profiles are available as all-mesh and all are available with an elastomer core to enhance compression characteristics and increase the deflection range.
Standard wire materials are monel, TCS (tin plated copper clad steel), stainless steel and aluminum. Wire selection should take into account attenuation potential, mechanical qualities, and corrosion resistance. The use of elastomer cores extends the operating range of the gasket.
