What is 4219PA51H01200?

4219PA51H01200 is a device used for RFI and EMI shielding. It is also known as fingerstock and gaskets and is made of a copper-based alloy material. It consists of a folded sheet of metal that fits into pre-drilled holes through which it interlocks to form a hermetic seal. This product is available in various thicknesses and widths and depending on the application, the material can be rated to meet various requirements of shielding performance.

Application Field of 4219PA51H01200

Common applications of 4219PA51H01200 include EMC compliance testing, radio base station and antenna site shielding, add-on electrical cabinet shielding, RF filter shielding, and all types of electronic enclosures for cellular base stations, broadcast and communication systems, audio systems, and aerospace.When selecting the material for contact, fingerstock and gaskets, it is essential to ensure that the shielding performance meet the required specifications. The combination of materials with specific conductivity, corrosion resistance, flexibility and hardness are other important parameters which must be considered when selecting this material.For all these application types, 4219PA51H01200 provide improved performance such as increased flexibility, superior shielding performance, and resistance to corrosion. The shape of the fingers can also be manipulated to improve the performance of the device.

Working Principle of 4219PA51H01200 

The working principle of 4219PA51H01200 is based on the reduction of radio frequency interference and electromagnetic interference by providing a closed boundary that blocks the transmission of RF and EMI signals. This is achieved by creating a continuous contact between the shield and the enclosure on which the shield is placed.The shield material is designed to reduce the signal strength of incoming RF and EMI waves by absorbing and reflecting them back in an opposite direction. This ensures that the signal received by the equipment placed inside the enclosure is minimal.The shield is designed to have a controlled impedance in order to ensure that the highest levels of reliability are achieved. As the contact area of the shield increases, the impedance also increases. This leads to an increase in the shielding effectiveness.

Conclusion

The 4219PA51H01200 product is designed to provide superior RF and EMI shielding performance in various application types. It is made of a copper-based alloy material and consists of a folded sheet of metal which interlocks into pre-drilled holes. The device is available in various thicknesses and widths and is optimal for EMC compliance testing, radio base station and antenna site shielding, add-on electrical cabinet shielding, RF filter shielding, and all types of electronic enclosures for cellular base stations, broadcast and communication systems, audio systems, and aerospace. The working principle is based on the reduction of radio frequency interference and electromagnetic interference by providing a closed boundary that blocks the transmission of RF and EMI signals.
