RFI and EMI - Contacts, Fingerstock and Gaskets

The 8863-0110-81 is a contact component used in applications requiring protection from radio frequency interference (RFI) and electromagnetic interference (EMI). The component is composed of contact fingers, gaskets, and a durable metal substrate. The contact fingers form a \'fingerstock\', providing a reliable connection between two mating components. This allows for a secure, protected connection between the two components, while blocking the passage of electrical signals from either component to the other.

The 8863-0110-81 component is specifically designed to provide reliable contact connections in environments such as military, aerospace, and electrical systems requiring a high level of protection against impingement from magnetic, electric, and radio waves. The contact points are composed of either metalized silicone gasket material or metalized plastic such as ABS, PEEK, or polyurethane. The material used in the contact fingers is typically copper or brass. The metal substrate is composed of a nickel alloy such as Tantalum, Nickel/Iron, or stainless steel.

The contact fingerstock is designed to securely connect two components, while providing a durable, reliable electrical connection. This is achieved by the inner core of the contact fingerstock, which is constructed of metalized silicone gasket material. This material has a hardness that provides a secure connection between the two components, while still allowing for flexibility and elasticity. Additionally, the metalized silicone gasket material ensures that the inter-component connection is secure even in environments with significant vibration or movement.

The gasket materials used in the component also provide protection against RFI and EMI. A metalized gasket material must be chosen that has a high interference reduction factor. The interference reduction factor indicates how well the material works to reduce interference. Materials such as copper, stainless steel, and nickel alloys with more than 75% total interference reduction factor (IFR) provide the most protection against interference. Additionally, all components must be securely bonded to each other to ensure the best protection against interference.

When installed correctly, the 8863-0110-81 component provides a secure, protected connection between two mating components. The connections are designed to remain secure and reliable even in environments with extreme vibration or movement. Additionally, the inclusion of metalized silicone gasket materials ensure that the component is protected against RFI and EMI. The metal substrate is constructed of more durable materials such as Tantalum, Nickel/Iron, and stainless steel, making the 8863-0110-81 one of the most reliable contact components available.
