SOFT-SHIELD 5000 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. A growing number of standard profiles and sizes provide flexibility when selecting a gasket for a specific application. Custom profiles or sizes can also be produced.

Each SOFT-SHIELD 5000 Series gasket consists of an electrically conductive fabric jacket over a highly compressible urethane foam core. The nickel-plated, woven nylon rip-stop jacket is selfterminating 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
  • 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
  • Asymmetrical profiles, as well as “C”, “V”, “P”, “D” shapes
  • No performance degradation after 10,000 compression cycles
  • Wide release liner for easy removal
  • Kiss-cut parts on release sheets for easy “peel-and-stick”
  • grounding applications
  • Self-terminating jacket – no sharp edges
  • Tested to Bellcore GR-64-Core Airborne Contaminants requirements
  • Custom lengths, custom profiles
Benefits
  • Cost-effective
  • Alternative to BeCu fingerstock
  • Pick and place installation
  • Technical application support
  • Global distributor/fabricator network
  • Application-ready custom parts (die-cut, spliced, etc.)
Note: Compression/deflection curves are typical. Dimensions shown do not include PSA thickness (0.005 inch typically). Actual size shown with PSA strip. All SOFT-SHIELD 5000 Series profiles can be supplied in either General Duty or UL 94V-0 rated versions.

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 onepiece gasket.

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.
