Competition in the equipment and devices industry is increasing each day with the advent of modern technology. To ensure emissions from these devices are contained within the necessary safety limits, RF and EMI shielding and absorbing materials are utilized. 2-6-1125 is a type of shielding and absorbing material, developed to effectively stem electromagnetic interference (EMI) and radiofrequency interference (RFI). When employed, the material works as a shield to reduce the radiation or reflections of EMI from the equipment. This article aims to discuss the application field and working principle of 2-6-1125, which falls under the category of RF and EMI shielding and absorbing materials.

Application Field of 2-6-1125

2-6-1125 is a composite material; it is made from absorbers of different types. These materials are generally used in specific applications, which include:

• Radiofrequency (RF) cable shielding
• Automotive industry
• High-speed network devices
• Telecommunication field

The material is applicable in situations where higher acoustical performance, by shielding the emanating noise in the frequencies from 500 MHz-2 GHz, is required. In this same frequency range, the 2-6-1125 composite can absorb electromagnetic waves and minimize radiofrequency interference generated by equipment and neighboring electronic systems.

Working Principle of 2-6-1125

2-6-1125 material consists of two parts: ferromagnetic material and dielectric material. The material functions based on the law of magnetic induction. It manages electromagnetic waves and reduces power by diverting RF energy from one point to another within the system. The EMI and RFI waves emitted from the device are transformed, via the ferromagnetic material, to a circular magnetic field. The circular magnetic field helps attract the EMI or RFI waves to the absorber, helping it remain within the device limits.

The dielectric material additionally helps reduce electromagnetic interference and attenuates the radio waves. The dielectric material absorbs the interference throughout the waveband, which prevents the wave from reflecting outward from the device boundaries. During the absorption of EMI and radiofrequency waves, the energy is slowly dissipated from the absorber, and converted to heat. This heat is dissipated to the environment, thus effectively reducing the interference generated from the devices.

Conclusion

2-6-1125 is an effective and reliable RF and EMI shielding and absorbing material, used for containing electromagnetic interference and radiofrequency interference. The composite material functions based on the law of magnetic induction, and is mainly utilized in radiofrequency cable shielding, automotive industry, high-speed network devices, and the telecommunication field. Depending on the applications, this material helps to absorb EMI and RF waves, and prevents the external reflection of the wave from the device boundaries.
