RFI and EMI - Contacts, Fingerstock and Gaskets

Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) are used in various applications today, ranging from automotive and industrial to medical and consumer applications. The same technology used to create these applications is used to protect vulnerable and sensitive components from interference. Contacts, fingerstock and gaskets play an important role in this protection and form the basis for many applications.

Types of Contacts

Contacts are short metal wires that are soldered, crimped or brazed to the surface of the components they protect. Contacts protect against EMI and RFI interference by providing a minimal level of insulation that blocks interface signals and reroutes them away from the vulnerable components. The contact material used for such purposes is determined by the environment the component will be exposed to, the amount of insulation needed and the size of the contact. The most common types of contacts used in applications today are tin-plated brass, stainless steel, silver-plated copper and aluminum.

Fingerstock

Fingerstock is a type of gasket material used to provide higher levels of protection than a contact alone. Fingerstock is typically made from materials such as silicone, rubber or foam and is designed to help reduce interference and prevent the accumulation of static charge. Fingerstock can also be used to seal contact surfaces, creating a secure connection that keeps contaminants out and allows for better performance. The thickness of the fingerstock is dictated by the application requirements and the material used to make the contact.

Gaskets

Gaskets are used to provide insulation between two surfaces. Gaskets are typically made from materials such as rubber, ceramic, plastic and metal. These gaskets protect the vulnerable components from the EMI/RFI interference generated by the contact.

0097078717 Application Field and Working Principle

0097078717 is an type of contact material which is used in the field of electromagnetic interference (EMI). It functions by providing a minimal level of insulation which blocks the interface signals and reroutes them away from the vulnerable electronic components. The contact material is made up of tin-plated brass, stainless steel and silver-plated copper. The thickness of the contact material is determined by the environment it is exposed to and the electrical insulation needed.In addition to providing a layer of insulation, the contact material is also used to seal contact surfaces. This helps to further protect the component from EMI/RFI interference, and it also helps to prevent the accumulation of static charge. Fingerstock is used in conjunction with the contact material to provide higher levels of protection against interference. The fingerstock is typically made from silicone, rubber or foam and is designed to help reduce interference.Gaskets are also used to add further insulation and protection against EMI/RFI. Gaskets are typically made of materials such as rubber, ceramic, plastic and metal. These gaskets provide a layer of insulation between the contact material and the vulnerable component.The combination of contact use, fingerstock and gaskets is what allows for a successful application to protect components against EMI/RFI. The combination ensures that components are properly protected from the interference and that they are also used safely and efficiently. This combination of protection is used in a variety of applications ranging from automotive and industrial to medical and consumer applications.
