These EMI shielding gasket strips and frame materials consist of a slotted aluminium extrusion carrier into which a solid or elastomer cored knitted mesh gasket is clamped. These ready-to-fit, semi-rigid gasket profiles help to avoid the problems often encountered when fitting adhesive-backed or plain mesh gaskets.
They can be supplied with dual gaskets, one on either side of the carrier, with one being an EMI shielded mesh gasket and the other an environmental seal. The aluminium extrusion acts as a limit stop, controlling the even compression of the gasket.
Lengths of knitted wire mesh with an aluminium carrier can be used on covers, door frames and other apertures where the surrounding metalwork is either insufficiently rigid or is very heavy duty and needs a robust, well anchored gasket which will not be affected by the stresses and shearing action imposed on conventional twinstrip gasket material.
Knitted wire mesh with aluminium carrier is generally supplied as straight lengths (up to 4m), as welded/jointed frames to suit specific apertures or as mitre cut sections ready to mount around cabinets, doors or hatches. The aluminium carrier is usually drilled and countersunk ready for screws or rivets or, in less stringent conditions, frames can be fixed using a high-bond pressure sensitive adhesive. Welding is possible but not recommended as damage to the knitted wire mesh or elastomer is very difficult to repair.
