RFI and EMI - Contacts, Fingerstock and Gaskets

The 4117AB51G09600 is a metal contact specifically designed for Radio Frequency Interference and Electro Magnetic Interference applications. These contacts are designed to be utilized with a variety of fingerstock and gaskets which help to create an effective solution to interference issues in an electrical system.

The contact itself is a 3.2 mm long brass spring contact which has a number of application uses. First, it can be used as a contact switch for electrical applications, actuating contact coils, limiters, relays and other remotely operated control devices. Secondly, it can be used as a contact in transceivers and other radio transmission devices, connecting and disconnecting antenna input/output and providing a mechanical disconnection for antenna and antenna cables.

The fingerstock and gasketact as the core elements of RFI and EMI protection. The fingerstock consists of metal plates, usually copper, connected together by an insulated material which acts to prevent the metal plates from shorting out when they come into contact or when they move away from each other. The gasket is a rubber material which provides electrical insulation, and this combination of elements is designed to protect the 4117AB51G09600 contact from interference. Fingerstocks can be varied in size and shape to create the most effective solution for a particular electrical system.

The combination of the contact and the fingerstock/gasket provides an incredibly efficient shielding of electromagnetic radiation, protecting the 4117AB51G09600 contact from interference in a range of applications. This shielding is made possible by the metal contact itself, the fingerstock and the gasket which provide the base layer of protection. The metal contact deflects electrical energy away from the contact area and the fingerstock and gasket further absorb the energy, providing an effective EMI shield.

This combination of contact elements also protects the contact from physical wear and tear caused by high frequency vibrations and shock. The fingerstock and gasket absorb the energy from the vibrations and shocks, again providing the contact with an effective shield against damage. This is especially important when the contact is used in harsh environments and where contact must be maintained for long periods of time.

The 4117AB51G09600 contact is an incredibly versatile and reliable contact, providing an efficient interface between electrical devices and providing reliable protection from wear and tear and interference. Utilizing a combination of the contact and fingerstock/gasket provides an incredibly effective solution for a range of applications, from electrical switching applications to radio transmissions.
