Contact Finger Spring

Contact Finger Spring

Product Name : Contact Finger Spring

Product Description

An EMC shielding gasket is simply a connector of two opposing metallic surfaces which makes them appear electrically as one continuous RF absorber. Nearly every area of the electronic marketplace may require some form of electronic shielding. Primary uses commonly include:
RF gaskets
Grounding
Electrostatic discharge
EMI/RFI shielding for emissions and immunity
High strength copper alloys, and in particular Beryllium Copper, meets the tougher, more demanding specifications
Product Benefits
Superior attenuation
High electrical and RF conductivity
Excellent resistance to stress relaxation
Excellent corrosion resistance
Superior endurance life
Accepts various plating for dissimilar metals compatibility
Excellent performance at elevated temperatures
High uniform strain characteristics
Moisture and UV resistant
Low current conduction; i.e. ESD
Cost-effective
