Multi-Point IIIa Expanded Screen Gasketing

Mutli-Point IIIa is a very thin, semi-flexible EMI/RFI shielding material, supplied with or without pressure seal. It consists of a severely expanded, diamond-pattern-cut Monel sheet with more than 220 contact points per sq. in. of surface area. An environmental seal is provided when the openings are filled with solid silicone. This material has very uniform thickness and can be routinely cut into connector gaskets with standard tooling.
