RFI and EMI - Contacts, Fingerstock and Gaskets

RFI and EMI (Radio Frequency Interference and ElectroMagnetic Interference) involve the emission and reception of electromagnetic energy, as well as the protection of electric devices from interference. Protection from RF and EMI is accomplished through the use of contacts, fingerstock and gaskets. Included in this protection are items such as 4283PA51H00200.

Contacts

Contacts include items such as relays, switches, connectors and contactors. The contacts may be used to electrically connect two or more conducting surfaces. The contact action is accomplished either by a mechanical action, or an electrical or electronic action. The purpose of contact action is to control the flow of electric current, voltage, and energy in order to activate, deactivate, signal or transfer signals between circuits.

Fingerstock

Fingerstock is a type of contact material used to provide a positive connection between two metallic surfaces. It is composed of a series of metal fingers arranged in a pattern, often referred to as “fingerstock”. The metal fingers are arranged so that when the contact surfaces come together, the fingers make contact with each other and create an electrical connection. The fingerstock may also include conducting surfaces which allow for a tighter connection, providing an electrical connection even after a period of flexing due to material movement.

Gaskets

Gaskets are seals that are used to prevent electrical contact between two components or surfaces. The purpose of the gasket is to provide a barrier between two different components, which is made of a flexible material. This material allows for the electrical current to be prevented from crossing the boundary of the two surfaces. The material is typically made from some kind of metal, which is formed into a particular shape in order to fit the mating surfaces and form a completely sealed boundary. The seal created by the gasket helps to reduce the possibility of electrical interference and the effects that it can cause.

4283PA51H00200

The 4283PA51H00200 application field and working principle involve the use of RFI and EMI contacts, fingerstock and gaskets. This component helps to reduce the possibility of interference from outside sources. It is a switch contactor assembly that is designed to be used in an application where the frequencies of the components being used are sensitive to EMI and RFI. The assembly helps to ensure that no external interference is able to pass through the assembly and affect the circuit or other components. The 4283PA51H00200 working principle is based on the contact action of the fingerstock, gasket and contacts used, which helps to reduce the possibility of electromagnetic interference. The gasket and fingerstock used in the assembly also help to provide a barrier that prevents passage of the external interference.
