Working Principle

58-CBSA-2.25X3.25X0.5 RF shields are manufactured using cold-rolled steel plates. The material is cut into specified shapes, then washed and coated with a protective material for enhanced durability and a corrosion-resistant finish. The shield consists of two plates that are arranged to form a shield cavity. The cavity is then filled with a high-performance absorber material, which acts as a barrier to RF signals. The shield acts as a one-way absorber, blocking out signals from outside and allowing signals to pass through from inside. This ensures that outside interference doesn’t affect the signals inside the shield cavity.

The absorber material inside the shield cavity contains various metal particles that are able to absorb RF signals. The absorber material prevents the signal from entering or escaping the shield cavity, thus providing effective RF signal shielding. Furthermore, the shield can be customized to fit specific equipment, such as smartphones, GPS systems and medical equipment. It also provides excellent weather-resistance for outdoor applications.

Conclusion

The 58-CBSA-2.25X3.25X0.5 RF shield is an excellent shielding solution for a wide range of applications. It offers superior protection against interference from external RF sources, while allowing signals from within to pass through unhindered. The shield consits of two plates made of cold-rolled steel and is filled with a high-performance absorber material for complete shielding. It is an ideal choice for communication, military, automotive, medical, and other electronic applications.
