The control of electromagnetic and radio frequency interference is a key technology in today's world of electronic age. The shielding to and from such interference is critical in light of the potential damage that may occur to systems and components. BalContact™ springs have been tested and proven to be effective shielding elements in the packaging of electronic enclosures. BalContact™ springs are characterized by their canted coils, which exhibit a unique deflection and force behavior upon compression. The springs are available as closed rings or straight lengths, in a variety of sizes and materials to fill demanding shielding requirements.


- High resistance to compression set provided by high deflection and resilience.
- High conductivity across interface preserved by highly concentrated forces at numerous contact points.
- Ensures consistent shielding despite surface irregularities and tolerance variations.
- Available in very small ring diameters and able to fit small package requirements.
- Easy installation - springs are self-retained in grooves.
- Easy assembly - provides low closure forces from light spring loads.
