RFI and EMI: Contacts, Fingerstock and Gaskets

Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) are two of the most common and destructive interferences in any device or system. When an electrical current passes through a material, it creates an electric and magnetic field that can interact with nearby objects. RFI is the unwanted interference caused by these electric fields while EMI is the unwanted interference caused by the magnetic fields. This interference can create static, hums, crosstalk and other unwanted noise that can disrupt or damage a system.The most reliable way to protect a device from RFI and EMI is to contain it in a shielded enclosure. This enclosure must be robust enough to block out any unwanted interference and keep the signals and environments within from being corrupted. To this end, several design solutions have been designed and developed, such as contacts, fingerstock, and gaskets.

Contacts

Contacts are small metallic pieces that when connected and grounded together, form a shield that prevents RFI and EMI from entering the device or system. This type of contact is typically used when connecting systems together or when connecting a device to another device. The contacts must be firmly grounded and of the highest quality to ensure quality performance.

Fingerstock

Fingerstock is a flexible metal strip that provides a continuous protective shield against RFI and EMI. It can be easily installed on any existing enclosure or it can be included as part of a custom designed enclosure. It is usually placed around the edges of an enclosure and should be securely mounted and grounded to ensure proper protection.

Gaskets

Gaskets are designed to create a tight seal between two mating surfaces. This prevents any air, dust, or other particles from entering or leaving the enclosure and prevents any unwanted interference from passing through. Gasket materials are typically made from foam, rubber, or metal and may be coated with a special material to increase their effectiveness at blocking RFI and EMI.

7707719090 Application Field and Working Principle

The 7707719090 is a type of gasket material that is specifically designed to provide maximum protection against RFI and EMI. It is made from a thicker foam material that is coated with a specially designed material that provides extended performance and protection. This material is ideal for use in high-traffic or highly sensitive areas where protective measures need to be taken to ensure no external interference disrupts operations. When this material is used, it must be installed properly and grounded properly to ensure optimal performance. Once it is installed, it will help protect any device or system from potential interference that may occur due to external sources. As an extra measure, a Faraday cage or grounding strap may be used to provide additional protection.

Conclusion

Protecting a device or system from RFI and EMI is crucial to ensure smooth and reliable operation of any given system. Contacts, fingerstock and gaskets are some of the most common design solutions used in this regard. The 7707719090 is a specific type of gasket material that provides enhanced protection from RFI and EMI. When installed properly and with appropriate grounding, it can help protect any system or device from potentially harmful external interference.
