Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) interference is a term used to describe the effect of electromagnetic waves on electronic circuits. It is commonly referred to as “interference”. RFI and EMI interfere with the operation of electronic circuits by creating noise or unintended changes in current or voltage in the circuit.

As such, manufacturers have developed components specifically designed to reduce or contain RFI and EMI interference in electronic circuits. One of these components is a 4223PA51G01490 contact item, commonly referred to as a fingerstock and gasket.

4223PA51G01490 Application Field

The 4223PA51G01490 contact item is a universally applicable contact used in a wide variety of electronic applications. It can be used in general purpose controller and electronic circuits as well as high frequency applications. It is especially useful where space is limited or where fast assembly and reassembly of components is needed.

It is also commonly deployed in the automotive, military, aerospace, and medical industries. Its reliable performance over a wide temperature range makes it a reliable choice for many types of circuits and applications.

4223PA51G01490 Working Principle

The 4223PA51G01490 contact item is composed of several components that can be configured in different ways to provide different levels of electrical isolation. The contact item has a two layer metallic component consisting of a base layer usually comprised of nickel or stainless steel and a surface layer which can be made of copper, silver, gold, or other conductive material.

In order to provide electrical isolation, air gaps are present between the surface and base layer. This air gap works to contain and reduce RFI and EMI interference. In addition, fingerstocks and gaskets are added to the contact item to further shield against radio frequency interference and electromagnetic interference.

The fingerstocks are added to the contact item and are made of copper or aluminum. The gaskets are also added and are made of rubber, plastic, or other pliable material. The rubber or plastic material provides a physical barrier against the ingress or escape of radio frequency signals.

The combination of these components is what makes the 4223PA51G01490 contact item so useful in shielding against RFI and EMI. It provides a reliable electrical connection without compromising on signal integrity. This makes the contact item a reliable choice for many types of electrical circuits.
