RFI and EMI - Contacts, Fingerstock and Gaskets

Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) can cause performance issues and outages in many commercial and industrial applications. To protect against these potential problems, a variety of shielding materials and solutions have been developed. Among the shielding solutions often used are contacts, finger stocks, and gaskets. In this article, we will discuss the most common solutions and materials used for shielding against RFI/EMI interference.

0078002117 Contacts

0078002117 contacts are small, low-profile conductive contacts designed for use in very tight confines. Popularly known as \'ground contacts\', they are designed to make efficient contact between two components in order to complete the electrical circuit. These contacts provide advanced EMI and RFI shielding and filtering and are commonly used in aviation, military, and NASA applications. The contacts are made of an alloy and are available in a variety of sizes, shapes, and configurations.

Fingerstock

Fingerstock is an elastomeric material designed to provide EMI and RFI shielding. This material has a porous surface that greatly reduces the amount of interference emitted, and also helps to stop electrostatic charges. It is flexible enough to shape into a variety of configurations, and strong enough to take the abuse of harsh industrial environments. Fingerstock is particularly useful in applications requiring constant movement, as the material doesn’t fatigue or tear easily. It is also useful in very tight spaces, and can be molded into the shape required by the application.

Gaskets

Gaskets are another important EMI/RFI solution. A gasket is a thin, flexible material used to seal two components together. Gaskets are used to provide a barrier between the two components, preventing electromagnetic and radio waves from passing through. This helps reduce the amount of interference that can be picked up by sensitive electronic components, and also helps preserve the integrity of the system. Gaskets are available in a wide range of materials and sizes, and are extremely durable. Gaskets are commonly used in automotive, industrial, and telecommunications applications.

Conclusion

RFI and/or EMI is one of the biggest challenges faced by engineers, especially in commercial/industrial applications. To address this challenge, a variety of materials and solutions can be used, such as 0078002117 contacts, finger stocks, and gaskets. These materials provide effective shielding and filtering of interference, and help to protect sensitive electronic components from potential damage caused by interference. By utilizing these materials and solutions, engineers can ensure that their designs are correctly shielded and perform reliably in a variety of environments.
