Environmental Seal/EMI Shielding Series
|
E/E HYBRID GASKET First Two-in-One Product of its Kind: E/E hybrid Gasket provides environmental seal and EMI shielding.
Schlegel Electronics Materials (SEM) E/E Hybrid Gasket is designed to meet both the environmental and EMI shielding needs of outdoor electronic and telecom cabinet manufacturers. The gasket features single-flange construction using a wire carrier and EPDM (Ethylene Propylene Diene Monomer) rubber core to provide durable environmental protection. Using a patented half-wrap manufacturing process, highly conductive nickel/copper cladding provides EMI shielding reliability. This combination of materials decreases the number of gaskets needed per cabinet.
The E/E Hybrid gasket features several advantages over the alternative shielding methods. The new gasket is designed to slide easily over metal flanges to help reduce installation costs, and is a good choice for retrofit applications. SEM's plating and coating technologies means there is no metal flaking with possible health concerns. Made of all recyclable materials, the SEM E/E Hybrid Gasket also avoids the out-gassing that can occur with silicone-based products.
