RFI and EMI - Contacts, Fingerstock and Gaskets

The 4247EF51K00080 is a part that is ideal for use in applications where there is a need for Electromagnetic Interference (EMI) and/or Radio Frequency Interference (RFI) protection. It is a shielding component that is designed specifically for use in applications where a contact must be made between two surfaces, such as a gasket on a door or seal on a cable. This part consists of two separate parts, a contact and a finger stock.

Application Field

The 4247EF51K00080 is typically used in a variety of applications that require EMI/RFI shielding as well as a contact between two surfaces. Examples include RF shielding in wireless devices, electronic enclosures, and connectors, as well as contact seals on aircraft, automotive, and industrial applications. This part is also suitable for use in applications where noise suppression is needed, such as audio equipment and medical devices.

Working Principle

The 4247EF51K00080 works through a combination of EMI/RFI shielding and contact. The contact portion of the part is composed of a corrosion-resistant copper-alloy material that is inserted into a finger stock. The finger stock is a rigid ring that has slots cut into it and is designed to create a continuous contact around the circumference of the two surfaces when it is pressed into them. This continuous contact is what provides the electrical contact between the two surfaces, allowing an electrical circuit to be established and allowing for EMI/RFI shielding.

The EMI/RFI shielding portion of the part is the outermost layer of the finger stock. This layer is composed of a magnetshield material that is designed to prevent any external electrostatic and/or electromagnetic fields from interfering with the electrical current flowing through the circuit. This layer of shielding material helps to ensure that the electrical current is not distorted or corrupted by any external interference.

Conclusion

The 4247EF51K00080 is a part that is specifically designed for use in applications where EMI/RFI shielding and a contact between two surfaces is required. It is composed of two separate parts, a corrosion-resistant copper-alloy contact and a finger stock with a magnetshield outer layer, which work together to provide a continuous contact between the two surfaces and to prevent any external electrostatic and/or electromagnetic fields from interfering with the electrical current flowing through the circuit.
