RFI and EMI - Contacts, Fingerstock and Gaskets

4056PA22101800 contacts, fingerstock and gaskets are a key component of Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) control systems. These components create an electrical connection between RFI and EMI shielding enclosures, straps, windows, doors and connectors, providing a low-frequency signal link to the electronic material contained within. These components are manufactured with an emphasis on performance, durability and reliability in a range of situations.

Application Field

4056PA22101800 contacts, fingerstock and gaskets offer a variety of applications within EMI and RFI control systems. It is used when an electrical connection needs to be created between equipment, components, and external objects. This can include:

• RF shielding at high frequencies
• Shielding from high voltage electrical surges
• Interference from external objects
• Creating electrical connections between cables, boards and components

The components can also be used in a variety of other applications, including as a seal on a variety of different enclosure types, e.g. sheet metal, printing and RF enclosures.

Working Principle

4056PA22101800 contacts, fingerstock and gaskets work by creating a conductive pathway between the two objects that are required to be electrically joined. Rather than simply bridging a gap between two objects, the contact is designed to have a set amount of electrical leakage. This prevents interference from undersirable electromagnetic radiation or voltage transients.

The contact is designed so that the connection between two components is affected by the amount of contact force applied, with lower contact forces providing a more reliable connection between the two components. The contacts also have a self-cleaning effect, which helps reduce the build-up of dust and dirt on the contact’s surface. This helps to ensure a reliable connection is maintained even in applications that are subject to dust and dirt.

The fingerstock is designed to provide a secure and reliable connection when connecting small objects. The fingerstock works by inserting into the hole, creating an electrical connection when placed into the housing or chassis of the device. The fingerstock is designed to have a low-resistance contact area, so that a high electrical current can be passed through without producing any additional noise due to contact resistance.

The gaskets used in this application are primarily designed to serve as a seal between components or chassis. These provide a range of benefits, including protection from environmental contaminants and protection from electrical surges. The gasket helps to ensure a tight, leakproof seal between components, so that a high degree of radio frequency noise, EMI or RFI shielding can be achieved.

Summary

4056PA22101800 contacts, fingerstock and gaskets are essential components in providing RFI and EMI shielding. They are designed to offer a reliable connection between two components or objects and are created from materials which are designed to provide a low resistance for electrical currents. Different types of contact can be used to suit different applications, such as RF shielding to provide signal integrity or gaskets to provide a tight seal between components.
