Beryllium Copper Finger Strips

Finger strip gasket or (spring) finger contact strip 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.

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.

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

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.

Design considerations/features

Finger strip sections are generally only suitable for indoor or controlled environments unless used inboard of suitable environmental protection.

As most sections are rivet mount or ‘clip on’ they lend themselves to efficient assembly on most sheet metalwork enclosures

They offer potentially very high shielding performance particularly if used in knife edge / channel configuration

Ideally suited for application where covers, doors etc are repeatedly opened and closed, particularly if there is a shearing or wiping action applied. This effect is useful as it ensures that contact faces are maintained in a clean condition

Sections exhibit excellent recovery – very low compression set

Be careful not to mount finger some strip sections in locations where it might be vulnerable to damage. For example, surface mounted fingers can be ‘snagged’ by clothing in doorways or access hatches

Applications

Typically used on 19” rack assemblies, communications cabinets, high performance screened enclosures

Single fingers or strip sections can be used for grounding or connection points
