DESCRIPTION SOFT-SHIELD 5 Series EMI gaskets are designed to meet the stringent shielding and mechanical performance requirements of today s commercial electronic enclosures, medical electronics, factory automation equipment, reprographics and grounding applications. SOFT-SHIELD 5 Series EMI gaskets consist of an electrically conductive fabric jacket over a highly compressible foam core. The nickel-plated-silver woven nylon rip-stop jacket is self-terminating when cut. Chosen for its exceptional compressibility, the foam core typically requires less than lb/in (.75 N/mm) closure force, making it especially useful for thin-walled plastic enclosures. Standard pressure-sensitive adhesive attachment tape (PSA) makes SOFT-SHIELD 5 Series gaskets a user-friendly and cost-effective design solution. FEATURES Typically requires < lb/inch (.75 N/mm) closure force 5 times lower than other gaskets >9 db attenuation from MHz to GHz Asymmetrical profiles as well as C, V, P, D shapes* Self-terminating fabric jacket No performance degradation after, compression cycles Adhesive ASTM D 4 lb/inch Peel Strength (9 Bend) (.7 N/mm) (min.) Continuous lengths or kiss-cut parts on polyester film sheets UL 94V- rated versions available BENEFITS Cost-effective Custom lengths available Alternative to BeCu fingerstock gaskets Pick and place installation available Technical application support Global distributor/fabricator network *Call for availability
