RFI and EMI - Contacts, Fingerstock and Gaskets

Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) are defined as any unwanted electromagnetic or radio emissions that adversely affect performance of an electrical/electronic circuit or system. Military, avionics and medical electronics are especially vulnerable to RFI and EMI interference. To protect these circuits and systems from such interference, shielding materials, such as contacts, fingerstock and gaskets can be used.

0077002802 contacts, fingerstock and gaskets are designed to prevent the entr into, or passage from, a housing that contains electrical or electronic circuitry from such interference. These materials are designed to provide an efficient and effective one-way pinching of the components, preventing the movement of any medium that may carry the interference.

Contacts are small pieces of metal or metalized material, which form a sliding contact and provide electrical and/or mechanical support. They are commonly used to provide electrical connections between circuits, by creating electrical paths that devices need to communicate with each other. Typically made of copper or brass, contacts are found inside or on the surface of electrical devices and connectors.

Fingerstock is a flexible material that is used to provide electrical insulation while providing a structural connection between components. Fingerstock can be made of various materials, such as aluminum, plastic, and rubber, which are designed to provide electromagnetic interference (EMI) and Radio Frequency Interference (RFI) protection. It is often used in conjunction with contacts and gaskets to form effective shielding as well as structural integrity.

Gaskets are a type of seal that act as a barrier between two or more surfaces to prevent the passage of air, water, dust, moisture, or any other material that may cause interference. Typically made of rubber, plastic, or metal, gaskets are used to keep out unwanted contaminants that could adversely affect the performance of an electrical or electronic circuit or system. They are also used to fix a component onto a board, creating electrical and/or mechanical connections, and providing physical protection.

0077002802 contacts, fingerstock and gaskets are used in the military, avionics, and medical electronics industries to provide the necessary shielding from RFI and EMI interference. The materials can be easily molded or cut to the desired shape, which provide efficient and effective one-way pinching of the components. By shielding these circuits and systems from RFI and EMI interference, these materials ensure the performance of an electrical/electronic circuit or system is not adversely affected.
