51H Fabric-over-Foam (FoF) EMI Gaskets

Laird 51H Fabric-over-Foam (FoF) EMI Gaskets provide excellent EMI shielding performance anywhere EMI issues occur. These gaskets are composed of electrically conductive fabric wrapped around a soft urethane foam core. They offer shielding effectiveness of >100dB across a wide spectrum of frequencies, and extremely low compression forces allow for the use of lighter materials. The 51H gaskets are supplied with conductive or non-conductive pressure-sensitive adhesive (PSA) and can be equipped with an extended-release liner (ERL) on the adhesive. They are halogen-free, UL 94V-0 rated, and RoHS compliant. Laird 51H FoF EMI Gaskets are ideal for use in cabinet applications, LCD and plasma TVs, medical equipment, servers, printers, networking equipment, and more.
