EMC-IP gasket with controlled compression stops 1230

EMC-IP gasket with controlled compression stops for EMI and EMP protection

This gasket is used for screwed connections for EMI and EMP protection. The water seal is made out of flame retardant neoprene foam. In the water seal are not only holes for bolts but also holes to make the foam more easy to compress. This makes it so that it can be used to screw thinner plates together without bending.

Around the bolt holes are compression stops to prevent the gasket overstretches. This makes it possible so that with a torque control the gasket is under exactly the right stress for water and EMI sealing during mounting. The bolt holes can be made at any distance. The compression stops can be out of metal or plastic. The thickness and width can change as well as the reduction of the compression force, without influence on the shielding capacities.
