EMI shielding Finger strip

Various plated finishes are available (e.g. tin, zinc, nickel) that can improve electrical contact properties, corrosion resistance, or improve wear characteristics.

One key benefit of finger strip is that D or curved profiles may be used in applications where there is a wiping or shear action on the gasket e.g. sliding door.

Most sections are based around a D profile. There are multiple variants in terms of size (profile height), design features, and mounting methods. Most commonly these include, self adhesive, clip on, rivet mount, slot mount or solder in place.

Finger strip (Finger stock) gaskets or (spring) finger contact strips are usually manufactured from beryllium copper foil.  Gasket profiles are resilient / compliant and can provide very low contact resistance between mating faces providing excellent EMI shielding performance. Profiles are available that are capable of coping with comparatively large variations in seam (gap) width. Very low closure force sections fabricated from light gauge foil are available.
