21M-CBSA-0.5X3.5X0.225

RF shields are protective devices which are used to provide protection to radio frequency emitting equipment by blocking out transmission or reception of radio waves that would otherwise interfere with electronic components and/or systems, as well as potentially harm people or disrupt critical operations. The 21M-CBSA-0.5X3.5X0.225 is an RF shield designed to protect sensitive radio frequency circuits from the effects of electromagnetic fields.

Application Field

The 21M-CBSA-0.5X3.5X0.225 is intended for use in the telecommunications industry, specifically to protect digital communication devices such as cell phones and other wireless devices from electromagnetic interference (EMI). This shield can also be used to protect sensitive electronic components such as receivers, data storage modules, and data processing modules from EMI.

Working Principle

When RF signals intersect with the protective shield, they are slowly absorbed by the shielding material into the shield’s interior, thus reducing the intensity of the signal in the protected area and preventing the signal from disrupting sensitive equipment. The material used in the 21M-CBSA-0.5X3.5X0.225 shield is a copper-based material that is designed to efficiently absorb electromagnetic waves, creating an area inside the shield that is virtually free from external interference. This shields both the interior and exterior of the device, protecting it from any external or internal EMI.

The 21M-CBSA-0.5X3.5X0.225 shield also features a small opening in the center of the unit which allows cables and wires to exit and enter the shield. This opening is designed to let signals through which require an opening, while maintaining the shielding effect. The material used in the construction of the 21M-CBSA-0.5X3.5X0.225 shield also helps in reducing the number of reflections within the protected area, thus increasing the overall efficiency of the shield.

Conclusion

The 21M-CBSA-0.5X3.5X0.225 is an efficient RF shield designed to protect digital communication devices from EMI. It can also be used to protect sensitive electronic components from interference. The shield features a copper-based material which helps to absorb RF signals and reduce the amount of reflected signal in the protected area, as well as a small opening which allows for the passage of signals. This RF shield is perfect for use in the telecommunications industry where protection from interference is essential.
