46W5E00720.NN00 application field and working principle

46W5E00720.NN00, also known as RFID contacts, fingerstock and gaskets, is the general name for three different types of radio frequency interference (RFI) and electromagnetic interference (EMI) shielding products. The three products have the same function, which is to prevent interference of interfering frequencies such as static electricity, indirect lightning, electric fields, etc. between electronic components inside the device.

Application Field

RFID contacts, fingerstock and gaskets can be used in various applications. Especially in fields with high reliability requirements such as automotive industry, military industry, industrial automation and medical, the products are widely used. For example, in the automotive industry, they are used in the production of automotive wiring harness, instrument panel, aerial and so on. In the industrial automation control industry, they are used for wire connecting and protection of PLC, servo motor, HMI and other related products. In military industry, it is used for all kinds of electronic products and electrical products.

Working Principle

The working principle of RFID contacts, fingerstock and gaskets is that in the certain area, the overlapping of the positive and negative poles of the electrical component produce electromagnetic field interference. Then, the interference can form a third mutual impedance to reflect part of the signal and reduce the impact of interference. It acts as an anti-interference inhibitor, ensuring the normal operation of the product electronic system.

• The first step is setting up a shield barrier, which can block the electromagnetism scattered radially, reduce interference and stabilize the operation current of the electrical component.
• The second step is to wrap the electrical component with product. It can strengthen the function of the shield barrier, reduce interference and protect the interior from damage.
• The third step is to coat grease, etchant or bonding to the product. It may improve the tightness of the product, improve the radiation effect and cause the shielded layer to form flame retardancy.

Conclusion

To summarize, RFID contacts, fingerstock and gaskets are widely used in various applications, providing great protection and ensuring the product\'s safe and reliable operation. The purpose is to prevent electromagnetic field interference, isolate shocking and high-frequency electromagnetic fields and static electricity from the electrical components, and to make the product work normally.
