Mesh Covered Elastomer Core Gaskets JHJ mesh covered elastomer core gaskets are used widely on electronic enclosures where there is a seam unevenness and where low closure forces are required. The compliable central core of the gasket takes up these divides and ensures excellent continuity between the mating surfaces. Ideal for frequently-opened panels & doors Because the central core does not allow a compression set, mesh covered elastomer core gaskets are particularly useful where panels and doors are frequently opened or assembled and disassembled. They are suitable for fixing by groove mounting, where they are held in place by sidewall friction. Some rectangular sections, where double-sided tape can be applied to the gasket itself, can be fixed using adhesive spots. Best shielding effectiveness The best shielding effectiveness is achieved when the gasket is compressed by 25-35% of its nominal height. It should be noted that dimensions given in our Data Centre are for mesh covered elastomer core gaskets only and that approximately 0.44mm should be added for each mesh layer. Features & Benefits Produced by knitting mesh covers over a central elastomer core Particularly useful with frequently opened panels and doors Suitable for fixing by groove mounting Rectangular sections can often be fixed using adhesive spots Best shielding effectiveness achieved with gasket compressed to 25-35% of nominal height Available in a wide range of cover materials Central elastomer core JHJ mesh covered elastomer core EMI shielding gaskets are produced by knitting mesh covers over a central elastomer core. A single cover of mesh is sufficient where only a moderate degree of shielding effectiveness is required, however a double cover is recommended for higher levels of attenuation. More layers of mesh can be added if required, but there are only limited benefits for more than two layers. Wide range of cover materials JHJ mesh covered elastomer core gaskets are available in a wide range of cover materials including Monel, Tin Plated Copper Clad Steel (SN-FE-CU), Tinned Copper, Stainless Steel, Silver-Clad Copper, Aluminium, Copper and Nickel. Other materials, such as Nickel-Plated Copper, Brass and Phosphor Bronze are available to special order. A number of central core materials are available, including neoprene sponge (as standard), silicone sponge, silicone tube and EPDM.
