Abstract

An EMI/RFI shielding gasket comprising a resilient elastomeric core enveloped with a fine, open format knit or braided wire mesh, and having a strip of pressure sensitive adhesive disposed lengthwise along a surface of the gasket.
This strip of adhesive allows the gasket to be removably fastened to an enclosure, circumventing the need for a metal clip and thus making the gasket lighter and less expensive than conventional gaskets.
