Working Principle

The 5411-0003-40-300 components are designed to provide superior shielding against external Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) sources. This is achieved by using two primary techniques – contact resistance and durability. They are designed to provide a low contact resistance, which is the resistance between two components when they come into contact with each other. This low contact resistance creates an electrical path between the two components, thus preventing external interference from reaching the other component. The contacts are also durably built, which makes them resistant to mechanical damage as well as external stress.

In addition, the components feature excellent shielding due to the use of a combination of materials. Specifically, the contacts feature a nickel/gold plated beryllium copper shield. This combination of materials creates an effective barrier against external interference.

To further increase the shielding capabilities of the components, they are designed with a wide variety of additional shielding features. These include gaskets, electromagnetic absorbing materials, and fingerstock. Gaskets are rubber rings that prevent external interference from reaching the components. Electromagnetic absorbing materials are used to absorb external interference before it reaches the components. Finally, fingerstock is used to create a secure mechanical connection between two components, thus further increasing the components’ shielding capabilities.

Overall, the 5411-0003-40-300 contacts, fingerstock, and gaskets provide excellent shielding in RFI and EMI applications. They are designed to provide a low contact resistance, high durability, and superior shielding capabilities. Additionally, they feature a wide variety of additional features that further enhance their shielding capabilities. As a result, these components are ideally suited for use in such applications as medical devices, radio communication systems, automotive applications, and aerospace applications.
