Fabric-Over-Foam Gaskets
Laird Technologies’ Fabric-over-Foam (FoF) 51N EMI gaskets provide excellent EMI shielding performance for customers where EMI issues occur. The 51N series EMI gaskets are composed of electrically conductive knitted mesh wrapped around a soft urethane foam core. They are supplied with either a conductive or non-conductive pressure sensitive adhesive (PSA), and can be equipped with an Extended Release Liner (ERL) on the adhesive. The 51N is a halogen-free, UL 94V0 rated product that can be created with cross-section profiles such as rectangle, D, C, P, T, knife, bell shapes, and others. The 51N EMI gaskets can be further customized to an application by die-cutting, hole punching, notching, etc. This gasket is not recommended for use in shear applications.
