RF Shields

Radio Frequency (RF) shields are devices used to protect electronic or electrical equipment from possible damage caused by electromagnetic interference (EMI). They do this by providing an extra layer of protection between the equipment and potentially damaging electromagnetic radiation sources. RF shields come in a variety of forms, from simple metallic shielding tape to complex cases and cages that completely surround the vulnerable equipment.

The type of RF shield needed to protect equipment from potentially damaging electromagnetic radiation depends on how the equipment is going to be used. Different types of shielding materials, such as metals, foams, and plastic films, are available to suit a range of applications and frequencies.

24-CBSA-3.75x4.0x0.2

The 24-CBSA-3.75x4.0x0.2 is one type of RF shield and is suitable for use in many applications. It is usually used to shield large electronic and electrical devices from electromagnetic interference. The shield, which is made from high-grade, low-profile foam and plastic materials, consists of two layers. The bottom layer provides the shielding from external EMI while the top layer makes the shield easy to install and remove.

The 24-CBSA-3.75x4.0x0.2 is typically used in applications where the device is particularly sensitive to EMI and needs protection from sources of radio frequency interference (RFI). This can include medical equipment, broadcast systems, satellite communications, and military and aerospace systems.

Working Principle

The 24-CBSA-3.75x4.0x0.2 works on the principle of eddy current shielding. This means that when electromagnetic radiation passes through the shield, it creates a circular magnetic field around the equipment and this field induces a current in the shield material. This current scrambles the incoming signal and reduces its amplitude.

The effectiveness of the 24-CBSA-3.75x4.0x0.2 depends on the size of the shield and the frequency of the radiating signal. The higher the frequency, the thicker the shield should be; the greater the shield thickness, the greater the attenuation of the signal. For this shield, a thickness of 0.2” is usually sufficient to provide adequate protection from most EMI sources.

The 24-CBSA-3.75x4.0x0.2 is an effective way to protect sensitive equipment from the harmful effects of EMI. With its high-grade materials and low profile, it is suitable for a wide range of applications and provides an effective way to protect equipment from RFI.
