Today’s cutting-edge technology requires new approaches to shielding and absorbing materials, such as 2-6-1194. This type of material employs a multilayered construction, using both conductive and dielectric layers, for optimal shielding performance and EMI/RFI absorption. 2-6-1194 shielding and absorbing materials combine reliable shielding effectiveness with superior physical characteristics, and are designed to meet demanding applications.
In general, the surface of shielding and absorbing materials should have a low electrical impedance (resistance), so that the electro-magnetic energy can be efficiently dissipated or attenuated. To specifically accommodate this requirement, shielding and absorbing materials use a combination of special dielectric (insulating) materials and conductive (grounding) materials to create an efficiently working shield. This shield is then layered into the material, with the conductive layer on the ‘outer side’ of the shield and the dielectric layer on the ‘inner side’. Each layer serves to efficiently dissipate the energy waves from the equipment.
So how specifically does the shielding process of 2-6-1194 work? The materials are optimized to function in various frequencies and at various amplitudes, with a combination of conductive and absorptive qualities. The conductive properties provide a very low electrical impedance across the entire surface of the material, while the absorptive properties enable the dissipation of electro-magnetic energy. Specifically, the conductive layer helps funnel energy waves to the ground connection and helps prevent the absorption of energy waves. The absorptive layer helps reduce the amplitude of the waves, and prevents excessive levels of energy waves from escaping from the equipment.
The superior performance of 2-6-1194 shielding and absorbing materials lies in their configuration of multiple layers, creating an effective shield. Rather than a single layer of shielding material, the multiple layers provide a more favorable electrical impedance. This impedance allows the energy waves to be efficiently dissipated and attenuated, without passing though the equipment. In addition, the two layers improve the total shielding effectiveness of the material, ensuring that the desired level of shielding and absorption is achieved.
This type of shielding and absorbing material is suitable for a wide range of applications, from commercial to industrial sectors. In most cases, engineers, architects and technicians use these materials for the prevention of electro-magnetic radiation from passing through the equipment. Applications can include cellular towers, radio base stations, medical facility shielding, and FCC or CE compliance measurement applications.
In the end, 2-6-1194 shielding and absorbing materials offer a superior performance that can help maximize the efficiency of any application. The advanced multilayered construction of these materials enables the efficient dissipation and absorption of electro-magnetic energy, providing reliable shielding and EMI/RFI protection. As a result, these materials are the ideal choice for projects involving complex electro-magnetic environments.
