3M AB5020 4.13" X 7.25"-25

Radio frequency interference (RFI) and electromagnetic interference (EMI) are two types of radiation that can interfere with the performance of electronic devices. RFI primarily comes from the transmission of radio waves, while EMI is produced by metal objects or electrical equipment. In order to prevent interference and maintain performance, shielding and absorbing materials can be used to minimize the effects of this radiation. One such product available on the market is the 3M AB5020 4.13" X 7.25"-25.

The 3M AB5020 4.13" X 7.25"-25 is a material that is specifically designed for shielding and absorbing EMI and RFI radiation. It is a single-layer flat foil structure made of conductive copper and other absorbent materials. The material is highly durable and provides excellent signal attenuation capabilities. In addition, it is resistant to high-pressure washdowns and offers a high level of flexibility for installation in tight areas. The product is also waterproof and has an adhesive backing to ensure a secure, long-lasting seal.

The 3M AB5020 4.13" X 7.25"-25 is designed for use in a variety of applications, including sealing high or low frequencies of electromagnetic energy in antennas, cables, conduit and waveguides. It can also be used in applications requiring signal shielding from radio transmitters, industrial equipment and other sources of electromagnetic interference. In addition, it can be used to protect sensitive military and space electronics against high-powered radar and electronic countermeasures. The material is also approved for use in the food, pharmaceutical, automotive and medical industries.

The working principle of the 3M AB5020 4.13" X 7.25"-25 is based on its ability to absorb and trap electromagnetic energy. The material absorbs the energy from the radiation, causing it to lose its amplitude in the region close to the material. Furthermore, the lower-frequency components are scattered downward and perpendicular to the surface, while the higher-frequency components are reflected away from the source, reducing the intensity of the signal in the area surrounding the source. This results in a signal strength reduction of approximately 90 dB, which is enough to stop the signal from disrupting any nearby electronic devices.

The 3M AB5020 4.13" X 7.25"-25 is an ideal choice for those looking for a reliable, cost-effective solution for shielding and absorbing EMI and RFI radiation. It is highly durable, resistant to high-pressure washdowns and provides excellent signal attenuation capabilities. Its adhesive backing makes installation easy, and it is approved for use in a wide range of industries. With its unique combination of properties, the 3M AB5020 4.13" X 7.25"-25 is the perfect product for protecting your electronic devices from interference.
