Material Notes:

The CFS range of contact finger strips are available in Beryllium Copper, Phosphor Bronze and Stainless Steel. Many plating options are also available. Contact finger strips are used to close the aperture between two surfaces and provide high EMI shielding effectiveness. The strips are very versatile in applications where low closure force is required such as enclosures.Material Specification: (Beryllium Copper) BeCu alloy 25(CA172) is used for maximum spring, strength and fatigue resistance.Information provided by P & P Technology
