RFI and EMI - Contacts, Fingerstock and Gaskets

The 4208PA51H02400 is a type of contact, fingerstock and gasket designed to provide effective solutions to shielding against both electromagnetic interference (EMI) and radio frequency interference (RFI). It is an integral part of the EMI/RFI shielding system, designed to minimize the potential for fields of radiation and noise from leaking into or out of an electronic enclosure.}

The 4208PA51H02400 consists of three main components: the fingerstock, the contact insert, and the gasket. The fingerstock is a thin sheet of metal foil-(typically copper or nickel) that is formed into an \'L\' shape that is \'fingered\' over the gasket. This shape provides a low resistance path for the EMI/RFI to cross the interface between the gasket and the enclosure.

The contact inserts are small terminals which are inserted into the fingerstock and the gasket for electrical contact between them. This ensures that the contact resistance remains below the threshold level that could lead to EMI/RFI becoming a problem. The inserts are typically made of terminal blocks or compression crimps.

Finally, the gasket completes the 4208PA51H02400 contact assembly. The gasket is a flexible material (silicone, neoprene etc) which provides the necessary physical characteristics to create a tight fit between the enclosure and the fingerstock. The gasket effectively seals off the EMI/RFI leak paths between the fingerstock and the enclosure and also provides mechanical stability to the assembly.

This combination of components ensures that the 4208PA51H02400 provides effective EMI/RFI shielding. The gasket provides a barrier to the metal fingerstock and the contact inserts provide a low resistance path for the signal. In addition, the contact inserts also ensure the electrical contact between the fingerstock and the gasket is maintained within the threshold level required providing complete protection from EMI/RFI radiation.

The 4208PA51H02400 is well suited for a range of applications where EMI/RFI shielding is critical. It is used in a variety of audio and video equipment, portable devices, computers, telecommunications equipment, and a wide range of other electronic devices. It is also used in military equipment, aircraft components, and automotive electronics applications.

In conclusion, the 4208PA51H02400 contact assembly is an important part of a complete EMI/RFI shielding system. It provides a combination of components which ensure effective EMI/RFI shielding and is suitable for a range of applications where EMI/RFI shielding is necessary. It provides a barrier to the metal fingerstock and the contact inserts provide a resistance path for the signal, providing efficient and robust EMI/RFI protection.
