Parker Chomerics SPRING-LINE® Fingerstock
Beryllium-Copper and Stainless Steel EMI Gaskets
Parker Chomerics beryllium-copper (BeCu) and stainless steel EMI gaskets (SPRINGLINE®) combine high levels of shielding effectiveness with a broad deflection range and low closure force properties. The spring finger wiping action can also help to reduce oxide build-up at mating contact surfaces when the gasket is used in applications demanding repeated openings and closings. The excellent performance qualities of beryllium-copper, including: high tensile strength, extreme operating temperature range and superb electrical conductivity, make it an ideal material for EMI shielding over a broad frequency range. For applications that are mechanically less demanding, stainless steel gaskets offer good tensile strength, extreme operating temperature range and good electrical conductivity. Stainless steel gaskets have higher compression set than BeCu,when used in demanding applications.
