3020706 RF/IF and RFID

Radio frequency interference (RFI) and electromagnetic interference (EMI) are two important factors that must be considered when designing electronic equipment. RFI and EMI contacts, fingerstock and gaskets are three components that are used to reduce or eliminate the effect of these interference phenomena.

RFI contacts provide a reliable shielding medium between two conducting planes or surfaces, preventing electromagnetic energy from passing from one side to the other. These contacts are often made of specialized materials such as silver-plated beryllium copper or brass alloys that are highly conductive and offer excellent low-frequency performance. RFI contacts are available in various sizes, shapes, and arrangements, and can be either pre-assembled or added to an existing assembly.

Finger stocks, also known as fingerstrips, are flexible metal strips with special dielectric surfaces, used to create a electrical connection between two metal surfaces. They are often used to reduce or eliminate RF signals passing through a gap or space within an assembly. Fingerstocks are highly conductive, typically made of brass or stainless steel, and can be cut to fit the assembly.

Gaskets provide a barrier, preventing leakage of energy between two connected components. These gaskets are constructed of materials with high physical strength and excellent electrical properties. They are also highly compressible, allowing them to be easily installed in tight spaces. Gaskets come in various forms and sizes, and can be used to seal around wires, cables, or openings in the assembly.

These components are essential for providing reliable and effective shielding from RFI and EMI, and play a critical role in ensuring a high-quality electronic design. Through the use of RFI contacts, fingerstocks, and gaskets, designers can reduce or eliminate interference effects within their assemblies, allowing them to achieve higher performance levels.
