Descripción completa del producto
Parker Chomerics SOFT-SHIELD® 4840 is an electrically conductive foam used for grounding of environmentally controlled applications. Consisting of silver-plated nylon fibers embedded into a low-density urethane foam, SOFT-SHIELD® 4840 is a low compression force gasket solution ideal for high volume applications such as consumer devices and industrial electronics. It is a more cost-effective version of the market leading SOFT-SHIELD® 4850, requiring lower compression forces but providing slightly lower conductivity (higher through resistance).
SOFT-SHIELD® 4840 is flammability rated to UL 94 V-0 with an operating temperature range of -40°C to 70°C. The optimized dispersion of conductive fibers within the foam matrix means that this material is electrically stable over many closure cycles which experiencing a low compression set (<15%). Provided with or without a conductive pressure sensitive adhesive, SOFT-SHIELD® 4840 is available in bulk rolls, cut sheets, or custom die cut shapes.
Product Features • Z-axis electrical conductivity • Good through resistance (<150 milliohms at 30% gasket deflection) • Average 60 dB shielding effectiveness from 20 MHz to 10 GHz • Low closure force (<2 PSI) • Stable electrical performance (through resistance) after multiple closure cycles • Low compression set (<15%) • Available in cut sheets, bulk rolls or custom die cut shapes • Non-nickel bearing material • RoHS, REACH and UL 94 V-0 compliant
Typical Applications • High volume consumer electronic devices • Servers, desktop PCs, and laptops • I/O panels, backplanes, connectors, access panels and rectangular/square strip gasket seals • Telecom infrastructure rack and enclosure components
