RFI and EMI - Contacts, Fingerstocks and Gaskets

Radio Frequency Interference (RFI) and Electro-Magnetic Interference (EMI) occur when a radio frequency signal is conducted through an electrical system, resulting in interference with other related systems. This interference can cause communication errors, engine malfunctions, audio distortion and data loss. The best way to prevent this interference is to use shielding devices. Shielding is a method of containing and controlling the electrical and radio frequency energy that may interfere with an electrical system or device.

One of the most effective ways to reduce interference caused by RFI and EMI is to use contacts, fingerstocks and gaskets. Contacts are devices that use pressure to close a circuit when in contact with another metal or surface. They provide uniform contact pressure and decrease the electrical resistance that could cause interference in the circuit. Fingerstock is a type of contact made from metal foil or stamped out of a metal strip. It is used to form a contact between two wires, reducing electrical resistance and EMI interference. Gaskets are sheets or strips of material that fit between two components of a device or system. They work as an EMI barrier by preventing the charge to escape and interfering with other devices.

0097031008 application field and working principle are related to the types of contacts, fingerstocks and gaskets typically used. Contacts are often made from copper, brass and aluminum materials and are useful for high frequency electrical applications. Fingerstocks are often made from stamped aluminum and steel and are most commonly used in ground connections and communications applications. Gaskets are often made from aluminum and steel, rubber and paper, and provide a good shielding against EMI interference and are useful in wiring systems and radio frequency applications.

The working principle of contacts, fingerstocks and gaskets is simple; they are used to minimize electrical resistance between two points in a circuit, thus eliminating EMI interference. Contacts use pressure to close the circuit and reduce electrical resistance. Finger stocks use a metal foil or stamped material to make a contact between two wires, creating a lower resistance path for the electrical current to flow. Gaskets create a barrier between components of a device, blocking the escape of charge which could interfere with other electronic devices or systems.

In summary, RFI and EMI can cause serious issues in electrical systems if not properly controlled. Contacts, fingerstocks and gaskets are useful devices that can be used to reduce interference caused by these factors. 0097031008 application field and working principle are related to the specific materials and configurations of these devices. Generally, these materials and configurations work together to reduce electrical resistance, thus preventing EMI interference and other potential problems.
