1. A gasket for providing electromagnetic interference (EMI) shielding and/or grounding of one or more electrical components on a substrate disposed within a passageway having a generally circular cross-section as defined by an electrically-conductive interior surface of a member, the gasket comprising:
inner and outer portions cooperatively defining a generally circular annular shape with a generally central opening;
the outer portion configured to be disposed circumferentially along and in electrical contact with the member's electrically-conductive interior surface in a first direction;
the inner portion configured to be disposed circumferentially along an edge portion of the substrate and in electrical contact with at least one electrically-conductive portion on the substrate in a second direction generally perpendicular to the first direction;
wherein the gasket includes a plurality of latch members circumferentially spaced-apart, and wherein the latch members are configured to be engagingly received and retained within corresponding circumferentially spaced-apart openings defined by a mounting component;
wherein the mounting component comprises a washer, wherein the washer and the member include corresponding fastener holes for receiving fasteners for attaching the washer to the member, and wherein the direction in which the fastener holes receive the fasteners is generally perpendicular to the first direction in which the gasket's outer portion electrically contacts the electrically-conductive interior surface of the member;
whereby the gasket establishes electrical grounding contact from the at least one electrically-conductive portion on the substrate to the member sufficient for EMI shielding applications.
