Mesh Over Elastomer

mesh_over_elastomerMAJR’s Mesh Over Elastomer Core gaskets offer the shielding effectiveness you can expect from a metal woven mesh gasket but also allows the gasket to compress in a way that you won’t find with a typical all mesh gasket. You can pick from a variety of material combinations depending on what sort of compression and shielding characteristics are needed for your specific application.

Features

  • Moisture and/or Dust Protection: Our silicone and neoprene elastomers under the appropriate pressure ensure  protection.
  • Wide Range of Materials:The designer can choose from a wide range of materials to satisfy EMI requirements while providing for corrosion protection and sealing criteria. See Table 2 for materials.
  • Excellent Attenuation Characteristics: The MAJR elastomer core shielding strip gives a high degree of attenuation in the H-Field, E-Field, as well as plane wave. The attenuation varies from over 95-100 dB in the E-Field to 35-85 dB in the H-Field.
  • Versatility of Mounting Methods: Designers have the option of using a groove design for holding the strip or using the mesh fin as a convenient way of strip mounting.
