RF and EMI – Contacts, Fingerstock and Gaskets

RF and EMI contacts, fingerstock and gaskets are essential components of any electrical assembly. In fact, they are an integral part of the complete package of electrical signal integrity that must be achieved in order to prevent interference and, ultimately, damage to equipment. The particular components that make up RF and EMI contact assemblies are readily available and manufactured according to certain specifications. For example, 8865-0105-72 is a high-frequency, gold-plated, fingerstock contact assembly that is specifically designed and manufactured for a variety of RFI applications.

Application Field

The applications associated with such contacts are both varied and numerous. In general, RF and EMI contacts, fingerstock and gaskets are used to provide signal integrity in such applications as aerospace, defense, medical, industrial, aerospace, telecommunications, automotive, communications, and other industries that require a reliable connection in order to limit interference between electrical devices. More specifically, the 8865-0105-72 contact assembly is designed to provide signal integrity for applications that require high frequency signals to be transferred between two devices.

Working Principle

The working principle behind such a contact assembly is relatively simple. It is based on the transfer of electrical energy from one device to another through an electrical conductor. In this case, the electrical conductor is the actual fingerstock used in the assembly. The fingerstock, in turn, is connected to the two devices via contacts that transfer the electricity between them. The gold plating on the fingerstock provides a conductive path that prevents interference between the two devices.

The fingerstock itself is plated with a special type of gold that is specifically designed to withstand high frequencies and provide a strong, reliable connection. The gold plating ensures that the connection will not corrode over time due to environmental factors or other conditions. Additionally, the gold plating helps to reduce the amount of stray RF signals that are the byproduct of high frequency electrical energy transfer. This helps to further improve the overall integrity of the connection.

Finally, the gasket used in the assembly helps to protect the assembly from physical damage that could potentially disrupt the connection. The gasket also helps to ensure that the electrical connection is maintained even when the devices are subjected to environmental changes, such as temperature fluctuations or other external influences.

Conclusion

RF and EMI contacts, fingerstock and gaskets are essential components of any electrical assembly. The 8865-0105-72 contact assembly is specifically designed for a variety of RFI applications and is constructed with components that are designed to transfer high frequency signals between two devices. The gold plated fingerstock ensures a strong, reliable connection while the gasket helps to protect the connection from physical damage. Together, these components offer a robust and dependable electrical connection that is suitable for a variety of applications.
