Different Emi Shielding and EMI Gasket Types

When buying gaskets, it is essential to understand the differences between different geometry and materials. Although both offer different characteristics, all gaskets can be broken down into four essential types. These four types are:

EMI Shielding & Gaskets
  1. Elastomers w/ conductive particles
  2. Spring fingers
  3. Fabric shielding gaskets (FSG)
  4. Knitted and wire mesh

These different types have their benefits, which are suitable for specific applications. Factoring important application needs, such as shielding performance, material compatibility of corrosion control, and compression forces will allow you to get better shielding gaskets. Other important considerations should include compression range, compression set, and environmental sealing.

Knitted gaskets and wire mesh are both designed from a wide range of metal wires (monel, aluminum, tin-plated copper-clad steel). These gaskets are cost-effective when running low-cycle applications. The gaskets offer maximum shielding effectiveness over a wide range of frequency ranges. Both types come in different sizes and shapes, which offers enduring resilience that has flexible mounting options. Conductive knit materials have close-knit stitching of metalized materials, which provides high-impact shielding that has a smooth, soft surface. Knitted mesh supplies user’s resilience for uniform and point-to-point contacts that need minimum compression forces.
