5500 Washer, cyinder and springs

Conductive 5760 rubber or 5770 foam. Materials are used for grounding, contact point, water tight rings or flexible springs. These can be used to contact PCB to housing.

Standard Nickel-graphite conductive rubber are used for EMI applications. The rubber is made conductive by incorporating small conductive metal particles throughout the material. It can provide an EMI-proof and watertight seal in narrow constructions. But they are also useful for EMP protection, wave-guide applications and against static electricity.

When in need of high deflection and low closure force we make conductive foams.
The material will return to almost its original height when released. The foam is covered with a layer of conductive polyurethane to protect it from environmental influences and to prevent burrs when cutting. Its conductivity is excellent in all directions (X, Y, and Z). Conductive foam is fire retardant as well as RoHS compliant.

Temperature resistance

Temperature resistance depends on the core material of the metal knit EMI/RFI gasket; ranges from -60°C up to 220°C are possible. These Metal knit EMI/RFI gaskets are insensitive to external influences and can withstand harsh conditions very well.
