Magnetic gasket for shielding against electromagnetic radiation

An electromagnetic interference (EMI) shielding gasket for use with removable and hinged panels of enclosures of electronic equipment, where it is necessary to limit the escape or entrance of electromagnetic radiation through a gap between the panel and enclosure. The gasket includes an elongated metal strip having a clip for easy attachment to the panel or enclosure. The strip carries flexible, electrically conductive sheet material that provides the shield. The sheet material is attached to the strip in a manner to provide a cavity therebetween along their length. A free floating elongated magnet is positioned within the cavity so that it urges the conductive sheet material against an edge of a mating piece of the enclosure by magnetic attraction. The structure conforms to surfaces with significant variations, thereby providing an effective shield, and also assists in maintaining the panel closed against the enclosure.
