EMI Shielding Gaskets suit large enclosures.

January 8, 2015

Provided in 0.125 in. and 0.250 in. thicknesses, Combination EMI Shielding Gaskets are fabricated from closed cell silicone sponge, silicone foam, and fluorosilicone sponge with edge bonded knitted monel wires. Gaskets are thicker and softer than filled conductive rubber EMI gaskets, making them suited for large enclosures requiring environmental gaskets and EMI shielding. Pressure sensitive adhesive aids installation, while monel mesh offers corrosion resistance and ability to resist oxidation.
