RFI and EMI shielding and absorbing materials have been around for quite some time. In recent years, the materials have become more advanced, offering improved performance in both RF and EM signal attenuation. One of the most popular materials for RF and EM shielding and attenuation is 2-5-CN3490, which is widely used in a variety of applications.

2-5-CN3490 is a two-layer metal mesh with a combination of copper and nickel. It is manufactured using an etching process, which results in a metal mesh structure with two layers of evenly spaced copper wires and a layer of nickel between them. The nickel layer provides the necessary conductivity and heat dissipation to ensure effective shielding and absorption of both RF and EM signals.

The mesh structure is also designed to provide an effective barrier against dust and moisture, making it suitable for a variety of applications. It is commonly used in antenna enclosures, medical equipment, data centers, industrial machinery, and test labs.

The working principle of 2-5-CN3490 is based on the principle of electromagnetic induction. It works by creating an electromagnetic field in the mesh which induces a current in the electrical wires connected to the mesh. This current produces an electromagnetic force which reacts with the wire, resulting in a strong shielding effect.

The effectiveness of the material can be further enhanced with the addition of an insulating layer such as foam rubber. The foam rubber acts as an additional barrier, restricting the electromagnetic waves from getting through. This helps to further reduce interference and improve the shielding effect.

2-5-CN3490 is also used in the manufacturing of RF shielding enclosures. The mesh material is often used as a part of the enclosure, forming the walls of the enclosure and providing an effective barrier against RF and EM radiation. It can also be used as a barrier between two components of a circuit, blocking any interference and improving performance.

The 2-5-CN3490 is a versatile material with many applications in RFI and EMI shielding and absorbing. Its unique mesh structure provides an electromagnetic field which induces a current in the wires connected to it, resulting in a strong shielding effect. It can also be used in the manufacturing of RF shielding enclosures, providing an effective barrier against RF and EM radiation. With the addition of an insulating layer, the effectiveness of the material can be further enhanced, improving the shielding effect and restricting interference.
