Fingerstock and gaskets are essential components in the Radio Frequency Interference and Electromagnetic Interference (RFI and EMI) industry. Used in a variety of applications such as shielding, coupling, and grounding, they help create a secure environment free of interference. The S7271-45R is a common fingerstock or gasket used in many of these applications. This article provides an overview of the S7271-45R application field and working principle.

Application Field

The S7271-45R fingerstock and gasket is an EMI/RFI shielding component, meaning it works to protect a device or system from excess electromagnetic interference. It is ideal for use in high frequency mechanical applications, providing enhanced performance in terms of attenuation and bandwidth.

The most common applications of the S7271-45R include the following:

• Shields and filter housings: The S7271-45R can be used in these applications to provide effective shielding and reduce the entry of external interference.
• Switch covers and access doors: The S7271-45R is often used in these applications to keep out dust, dirt, debris, and water. By providing an effective seal, this fingerstock also helps protect against the entry of electromagnetic interference.
• Cable penetrations and cable glands: The S7271-45R can be used in these applications to create an effective seal that blocks the entry of external interference. This fingerstock is also beneficial in reducing signal radiation and crosstalk.

Working Principle

The working principle of the S7271-45R is based on the concept of an electrically isolated conductive path, or a Faraday cage. This path is created by the fingerstock or gasket when it is placed between two electrical elements or components. The S7271-45R is a highly conductive, non-metallic material with high signal attenuation, meaning it can effectively block or reduce external interference.

In addition to the electrically isolated conductive path, the S7271-45R also features EMI absorbing properties. This means that, when the fingerstock or gasket is in contact with a metal surface, it can absorb and attenuate the surface’s electromagnetic fields. This helps to reduce or eliminate external interference and maintains a secure environment free of interference.

Overall, the S7271-45R is an ideal solution for high frequency mechanical applications that require enhanced performance in terms of signal attenuation and bandwidth. It is used widely in EMI/RFI shielding applications to create a secure environment free of external interference.
