Optimal Frequency Attenuation for Your Application
ZILLKON contact strips made from spring-grade metals, metallized gaskets, or plate gaskets provide ideal protection against interference frequencies and prevent the generation of disruptive signals within housings.
Our extensive range of contact springs and sealing solutions allows standard configurations to be adapted for most applications.
The contact springs attenuate frequencies from 100 MHz to 2 GHz with a shielding effectiveness of 75 to 120 dB, depending on the compression of the contacts.
We offer a wide variety of designs, materials, and surface finishes and are available to provide tailored technical consultation.
Standard contact spring strips operate effectively up to a field of 500 MHz and achieve attenuation levels of –75 to –120 dB. In the microwave frequency range, attenuation can be successfully achieved using special contact springs. These springs are customized to match the housing, cavities, or grooves.
Profile gaskets and meshes cover the full range of frequencies. Over time, the material adapts to the contours but loses contact pressure and is therefore less dynamic in use compared to contact springs.
Plate gaskets can consist of different material layers and thicknesses, covering all frequency ranges. As a result, they offer more dynamic performance than profile gaskets—similar to mesh materials.
Our foam sheets are not only self-adhesive but also equipped with a neoprene protective layer that resists all liquids.
