RFI and EMI - Contacts, Fingerstock and Gaskets

Radiated fields, such as radio-frequency interference (RFI) and electromagnetic interference (EMI) are a form of ambient energy that can disrupt the electronic performance of any device. The 4208PA51G07200 has been designed specifically to protect against these types of interference. Contacts, fingerstock and gaskets form part of the 4208PA51G07200 solution and provide shielding in your most essential electronics.

Application Field

The 4208PA51G07200 solutions provide excellent protection against RFI and EMI for a variety of applications. A few examples of these applications include agricultural instrumentation, military equipment, industrial control systems, medical equipment, automotive electronics, cellular radios, and GPS systems. These solutions protect any device that is susceptible to these types of interference by providing strong shielding performance.

Working Principle

The 4208PA51G07200 works by creating a physical barrier between the electronic components and the radiated energy from RFI and EMI. It does this by using contacts, fingerstock, and gaskets that are specifically designed to maximize RF and electrostatic shielding.

Contacts are spring metal clips that attach to the PCB near the sensitive components. These clips are placed so that they form a complete connection between the ground plane of the PCB and the chassis of the device. This complete connection helps to create a low resistance path for the ambient energy to flow into the ground, thus shielding the sensitive components.

Fingerstock is an exceptionally thin yet strong metal material that wraps around the edges of the shielded unit, creating an EMI gasket. This gasket creates an effective barrier between the shielded unit and the ambient energy. The EMI gasket also acts as a reinforcement to the contacts, helping to ensure a complete connection between the PCB and the chassis, and maximizing the performance of the shield.

Gaskets are also used in the 4208PA51G07200 solution. These are typically made from either silicone or foam rubber. Gaskets are placed in between the PCB and the chassis, ensuring that there is a secure connection between the two, while also maintaining the required shielding performance.

The 4208PA51G07200 solution is an excellent choice for protecting any device from RFI and EMI interference. The combination of contacts, fingerstock, and gaskets ensure that the device is shielded from these ambient energies, helping to maintain the highest level of electronic performance.
