ABSTRACT:
One embodiment of a gasket for shielding electromagnetic interference passing through a seam between first and second electrically conductive bodies includes a base for securing the gasket to the first, electrically conductive body and a multiplicity of discrete, elongate, metallized filaments projecting substantially perpendicularly from the base so that a substantial amount of the filaments contacts the second, electrically conductive body when electromagnetic interference passing through a seam between the bodies is to be shielded. The gasket further includes structure, arranged with the base, for providing an electrically conductive path for conducting electric current between the filaments and the first, electrically conductive body. In this manner, energy absorbed the shielding member as a result of the shielding of passing electromagnetic interference can be dissipated to ground through the first, electrically conductive body. The gasket is particularly useful for shielding electromagnetic energy passing through seams between electrical apparatus housings and door or access panels in such housings.
