® SOFT-SHIELD 2000 Series Conductive Yarn over Foam EMI Gaskets ■ >70 dB attenuation from 20 MHz to 10 GHz ■ Requires <1 lb/inch (0.175 N/mm) closure force ■ No degradation in performance after 10,000 compression cycles ■ Self-terminating – simply cut to desired length ■ Won’t crease or wrinkle in storage ■ <25% compression set at 50% deflection, 22 hr. at 158°F (70°C) ■ Pressure-sensitive adhesive (PSA) for quick mounting ■ Extended PSA release liner available ■ Rectangular, square or “D” profiles ■ Available kiss-cut on film sheets 10 SELF TERMINATING, LOW CLOSURE FORCE COMPRESSION-DEFLECTION 0.455 SOFT-SHIELD 2000 Series gaskets consist of silver-plated nylon yarn knitted as the outer layer over a highly compressible, thermoplastic EPDM foam core. Through a special treatment process, the yarn jacket is secured to the core. This self-terminating outer layer eliminates the need for secondary termination efforts and metal particle debris associated with the cut ends of common wire mesh gaskets. 2.2 0.385 Gasket tested: 0.190 in. wide x 0.130 in. high (4.83 x 3.30 mm) 1.8 0.315 1.4 0.245 1.0 0.175 0.6 0.105 0.2 0 0.035 0 The low closure force characteristic of SOFTSHIELD 2000 Series gaskets allows enclosures to be designed with fewer fasteners or thinner panels. The knitted conductive layer provides excellent EMI shielding in the 20 MHz to 10 GHz range. 0 20 40 60 Deflection (%) Compression N/mm Compression lb/inch 2.6 Figure 1 SHIELDING EFFECTIVENESS Part No. 01-1392-6791 120 Attenuation (dB) Configurations: Standard SOFT-SHIELD 2000 Series gaskets include both rectangular and “D” cross sections. Gaskets are provided in bulk on spools or cut to custom lengths. For attachment to flanges or other mounting surfaces, these gaskets are available with pressure-sensitive adhesive for quick, efficient application. An extended PSA liner is available to ease paper removal. Parts can be provided kiss-cut on sheets for low cost gasket installation. 100 80 60 40 Test Procedure TP-08 20 0 10 100 1000 10000 Frequency (MHz) Figure 2 ORDERING INFORMATION Use the following part numbers to order SOFT-SHIELD 2000 Series gaskets: 01 – 1392 – XXXX Gasket profile (see below) NOTE: Change the 3 to 2 if ordering gaskets without pressure-sensitive adhesive backing.
