A growing number of standard profiles and sizes provide flexibility when selecting a gasket for a specific applica驭tion. Custom profiles or sizes can also be produced. Each SOFT-SHIELD 5000 Series gasket consists of an electri-cally conductive fabric jacket over a highly compressible urethane foam core. The nickel-plated, woven nylon rip-stop jacket is self-terminating when cut. Chosen for its excellent compressibility, the foam core typically requires less than 1 lb/in (0.175 N/mm) closure force, making it especially useful for thin-walled plastic enclosures. Standard pressure-sensitive adhesive attachment tape (PSA) makes SOFT-SHIELD 5000 Series gaskets a user-friendly and cost-effective design solution. Every profile in the SOFT-SHIELD 5000 Series can be provided in a General Duty version or a UL 94V-0 rated version, as needed, with no difference in performance. FEATURES  Choice of General Duty or UL 94V-0 rated versions Օ Typically require <1 lb/in (0.175 N/mm) closure force - 5 times lower than other gaskets  >90 dB attenuation from 20 MHz to 10 GHz Օ Asymmetrical profiles, as well as "C", "V", "P", "D" shapes  No performance degradation after 10,000 compression cycles Օ Wide release liner for easy removal  Kiss-cut parts on release sheets for easy "peel-and-stick" grounding applications Օ Self-terminating jacket - no sharp edges  Tested to Bellcore GR-64-Core Airborne Contaminants requirements Օ Custom lengths, custom profiles BENEFITS  Cost-effective Օ Alternative to BeCu fingerstock  Pick and place installation Օ Technical application support  Global distributor/fabricator network Օ Application-ready custom parts (die-cut, spliced, etc.) With an extensive choice of profiles and sizes, SOFT-SHIELD Gaskets are supplied as strips or kiss-cut parts on film release backers, or individual pre-cut pieces. Pressure-sensitive adhesive is standard. Single-piece picture frame gaskets also can be fabricated from continuous lengths, incorporating integral pre-cut notches for fasteners. (See page 2.) CONFIGURATIONS Gaskets are supplied in standard 8-foot lengths or cut-to-length strips. Depending on the profile, gasketing can also be supplied on spools. For rapid peel-and-stick grounding applications, the material is supplied as kiss-cut parts on polyester film release backers, or as individual pieces. Chomerics also fabricates single-piece, spliced picture frame gaskets from continuous lengths. With their fully jacketed surfaces, these gaskets are ideally suited for low closure force applications that require 360° EMI shielding, or the ease of installing a one-piece gasket (see next page). Chomerics' Applications Engineering department welcomes the opportunity to provide assistance with design and prototype fabrication of SOFT-SHIELD 5000 Series EMI Gaskets in custom profiles. continued
