RFIs and EMIs or Radio Frequency Interference and Electromagnetic Interference are the electromagnetic radiation that can disrupt any radio or electrical equipment. These electromagnetic waves can easily penetrate through solid objects like a wall and cause interference in both the radio signals and the electrical equipment in the vicinity.

One of the most effective ways to protect against this interference is to use high-quality, specialized fingerstock, contacts, and gaskets for EMI/RFI shielding. 4198PAH1K00480, produced by Harwin Inc, is an example of one such high-grade material designed to protect against RFIs and EMIs. This material is particularly suitable for applications where the environment would otherwise be plagued by frequent and high-amplitude EMI and RFI.

The 4198PAH1K00480 contact spring is made up of a base material that contains silver, bronze, and a special elastic element. This combination of materials gives the contact spring excellent electrical conductivity and two times the normal RF insulation performance. It also has a contact resistance of 0.8mΩ maximum making it ideal for a variety of electronic applications.

The contact spring also has a visible electromagnetic field interference (EMI) absorption rate of over 110dB at multiple points of the frequency band. This makes it suitable for signal interventions in high and low frequency applications. It also has a resonance frequency of 1GHz, which means the contact spring is capable of reducing the EMI/RFI noise within the equipment belonging to the application.

The contact spring resembles a fingerstock, with the base made of silver and bronze with an additional elastic element running along the side. This combination gives the material strength and flexibility to ensure the proper functioning of the contact spring. The fingerstock can also be pressed down when working with precision mechanical components, while the flexible arm ensures that the contact is made with the other component.

The contact spring comes with a gasket made from flexible polyester with a elastomeric coating. This gasket is an important component of the 4198PAH1K00480 contact spring as it provides an additional layer of protection against the RFIs and EMIs for the mechanical components. The combination of the fingerstock and the gasket ensures a strong bond between the two components while also providing adequate protection against RFIs and EMIs.

Overall, the 4198PAH1K00480 contact spring is an ideal EMI/RFI shielding material for precision applications. It is made of a combination of silver and bronze metallic alloys to give it excellent electrical conductivity and high RF insulation performance. It also comes with an elastomeric gasket to further protect against RFIs and EMIs. Moreover, its resonance frequency of 1GHz makes it suitable for EMI/RFI reduction in numerous applications.
