RF shields are critical components in technology-related applications that help protect delicate electronics from electromagnetic induction (EMI). RF shields help manage the levels of RF energy by controlling or eliminating their emission. The designation 20-CBSA-2.25X4.25X0.2 is applied to a series of RF shield products which enjoy increasing levels of popularity in a wide variety of commercial and military applications. In this article, we will discuss the application field and working principle of the 20-CBSA-2.25X4.25X0.2 series of shields.

One of the primary applications of the 20-CBSA-2.25X4.25X0.2 series of RF shields is in the industrial market. These highly effective devices function to reduce the levels of ambient RF energy and other related electromagnetic noise from electronic components such as machinery, transformers, ovens and welding supplies. This protection of the sensitive electronics within the industrial environment is beneficial for increased efficiency and productivity, as well as a higher level of safety.

Another application of the 20-CBSA-2.25X4.25X0.2 series of RF shields is in the medical and health care market. due to the sensitive nature of medical technologies, the same type of protection afforded to the industrial market is applied. To ensure the accuracy and efficacy of the data collected from such devices as X-ray and MRI machines, it is necessary to reduce the amount of RF energy passing through them.

The 20-CBSA-2.25X4.25X0.2 series of RF shields is also finding application in the military market. As such, the shields are designed to protect sensitive electronic instrumentation from high levels of RF energy and other electromagnetic interferences (EMI). By blocking such EMI, the reliability of the equipment is improved, enabling troops to operate with minimal usage compromises and other mission-critical information.

The working principle of the 20-CBSA-2.25X4.25X0.2 series of RF shields is based on the concept of a Faraday cage. A Faraday cage is a metallic structure that acts to block external RF energy from entering an enclosed space. The total attenuation (or shielding effectiveness) of a Faraday cage is determined by a combination of the magnitude and frequency of the incoming RF energy, as well as the size and shape of the cage itself. Typically, a Faraday cage should provide a shielding effectiveness of 100 decibels.

RF shields of the 20-CBSA-2.25X4.25X0.2 series offer an additional level of protection in the form of an integral RF window. This RF window allows an RF signal to pass through the shield while still providing a high level of shielding effectiveness. This window is typically made from a thin conductive member (such as copper or aluminum) that has been etched or treated to permit the passage of the RF signal while still protecting the electronics from the risk of EMI.

In summary, the 20-CBSA-2.25X4.25X0.2 series of RF shields provides an effective method of reducing the levels of ambient RF energy and other related EMI from entering sensitive electronics. These products can be applied to a wide variety of commercial and military applications, ranging from the industrial market to health care and the military. The working principle of the products is based on the concept of the Faraday cage, while the integral RF window provides an additional level of protection by allowing RF signals to pass through the shield while still providing a high level of shielding effectiveness.
