Beryllium copper fingers combine high levels of EMI shielding effectiveness with spring-finger wiping and low closure force properties.

Beryllium copper’s high tensile strength, excellent anti-corrosion properties, and superb electrical conductivity are ideal for shielding over a broad frequency range.
The BeCu gaskets are available in bright tin, bright copper and bright nickel finishes.

For low compression grounding contacts, individual fingers are available with pressure sensitive adhesive for convenient pick-and-stick application.
