EMI shielding gasket introduced

08 August 2008

Soft-Shield 4850 from Chomerics Europe, a division of Parker Hannifin, is an EMI shielding gasket that utilises multi-planar, Z-axis conductive foam technology to help it deliver shielding effectiveness of 95dB average. The UL 94 V-0 certified material is ideal for use as a shielding method in consumer and commercial electronics, telecom and information technology applications such as backplanes, I/O panels, and access panel cabinet seals.

Soft-Shield 4850 uses electrically conductive silver plated fibres (no nickel material is used) optimally dispersed within a low density foam to give a low closure force, cost-effective shielding application with excellent through-resistance and compression set properties.

In order to simplify assembly, provide gasket adhesion and optimise electrical interface resistance, Soft-Shield 4850 can be specified with a selectively coated pressure sensitive adhesive (PSA). The material is manufactured in rolls and can be easily and economically converted into profiles applicable for I/O panels, backplanes, connectors, access panels as well as rectangular or square strip gasket seals.

Soft-Shield 4850 is fully RoHS compliant and has an operating temperature range of -40ºC to +70ºC.
