The knitted wire mesh EMI/RFI shielding gaskets consist of a layer of knitted electrically conductive metal wires attached to a low-closure force rubber or elastomer core. For heavy-duty applications like EMP or high temperatures, a full metal version is available. Sometimes a Metal knit EMI/RFI gasket is combined with an environmental seal to provide IP rating, depending on the materials used.
Knitted wire mesh gaskets provide a cost-effective solution to high shielding performance applications in the magnetic and electrical fields, including EMP. The gaskets can be made either completely from knitted metal mesh or from knitted metal mesh over an elastomer core which allows recovery after compression.
For high-frequency shielding, foil-based gaskets like Amucor Shield will perform better, because of their much larger contact surface.
