Radio frequency interference (RFI), also known as electromagnetic interference (EMI), is the name given to undesirable levels of electromagnetic radiation created by sources such as electrical components, radio transmitters, and power lines. This radiation affects nearby receivers and can create noise or data errors. In order to prevent this interference, contacts, finger stock, and gaskets can be used to contain and reduce the interference.

302115105 Contacts

Contacts are electrical connections that allow two components to communicate with each other. They are typically made of copper, gold, or other materials that conduct electricity. RFI and EMI shielding contacts are typically constructed using a specialized combination of alloys that is designed not only to provide good electrical conductivity but also to reduce the level of radiation emitted. These contacts are constructed in such a way as to minimize their effectiveness in acting as an antenna for the radiation.

302115105 Finger Stock

Finger stock are a type of contact that is used to connect two components that have a small gap between them. It consists of a series of thin metal plates or fingers that are designed to conform to the two components they are connecting. The finger stock creates a physical barrier between the two components, which helps to reduce the amount of RFI and EMI emission. The finger stock is often combined with an insulating material, such as silicone or Teflon, to further reduce radiation levels.

302115105 Gaskets

Gaskets are used to create a seal between two components or devices. They are usually made from materials such as EPDM or silicone, but can also be made from other materials such as rubber or cloth. The gasket is designed to create a tight seal between the two components, which reduces the amount of radiation emitted. This type of protection can also be used in combination with contact and finger stock for additional protection.

RFI and EMI can be a major issue for many systems and devices. By using the right types of contacts, finger stock, and gaskets, the amount of radiation can be greatly reduced and the system can operate more reliably. These components provide shielding effectiveness by helping to contain and reduce the radiation levels.
