Product Specs
Specification
Our EMI Shielding Springs are available in lengths (for simple or complex groove configurations) and welded rings from 0.030” (.76mm) ID. Since every spring is designed to meet the unique requirements of your application, we don’t stock a “standard” size and type. But we do maintain a database of commonly-requested diameters and cross-sections, which can serve as a baseline for streamlined customization.
The table below outlines the standard dimensions for EMI Shielding springs.
These dimensions are subject to standard manufacturing tolerances, which can be provided upon request.
