Radiation from electrical and electronic equipment is a key concern for many industries, particularly in the electronics and aerospace sectors. To protect against harmful interference, RF and EMI-Contacts, Fingerstock and Gaskets can be used to shield devices, cables and components from electrically-activated energy emission. There are three main types of contacts that provide radiation protection:

RF Contacts (Radio Frequency Contacts)

RF Contacts are designed to block or reduce interference from and to RF equipment. These contacts typically use a conductive elastomer material to provide a low-impedance path from the source to a receiving antenna. They are used to reduce the impact of RF noise generated by electronic equipment from affecting other nearby devices or systems.

Fingerstock (Strip Copper Gaskets)

Fingerstock are used to prevent electrical interference, or EMI, between electronic components due to currents induced by near-field radiation. The use of strip copper fingerstock gaskets creates a Faraday cage around the components, which helps direct the electromagnetic path of the interference away from the components.

EMI-Contacts (Electromagnetic Interference Gaskets)

EMI-Contacts are a type of self-adhesive contact which provides essential shielding against interference from nearby electronic devices. They ensure a reliable connection and are designed to be easily and quickly installed. The contact covers the connection area so that the radiation generated by the devices does not escape.

Application Field

RF and EMI-Contacts, Fingerstock and Gaskets can be used in a wide range of applications, including: aerospace, defense, medical, automotive, power electronics and communications. They are commonly used in PCB assemblies where fouling is an issue, and they provide a solution to filter out both external and internal noise. They are also used in automotive, military and aerospace applications for shielding sensitive and expensive electronic components from harsh external environments. Finally, they are often used in consumer and industrial electronics for reliable shielding against EMI.

Working Principle

The primary purpose of RF and EMI-Contacts, Fingerstock and Gaskets is to reduce electromagnetic interference between devices. This is achieved by blocking or reducing the incoming energy emitted by nearby sources and by reflecting some of the energy back to the source. The contacts also act as barriers, preventing the emission of radiation from the equipment themselves. They can also be used to direct the flow of the radiation so that it is directed away from other nearby devices.

RF and EMI-Contacts, Fingerstock and Gaskets are widely used in many industries, thanks to their reliable shielding against undesirable emissions. They are also easy to install and provide a cost-effective solution to reduce interference and maintain the integrity of electronic circuits in harsh environments.
