RF and EMI shielding consists of various components that work together to create a tight, robust shield that blocks the transmission of electric and magnetic fields. One of the components is contacts, fingerstock and gaskets, and one example of this type of product is the 440 428-2.

The 440 428-2 is a brass fingerstock gasket made specifically for creating a comprehensive RF/EMI shield. It provides uniform electrical contact between either two or three components, ensuring reliable shielding of radio frequencies and electromagnetic fields. The gasket is designed to fit most mated parts, including grooves, slots and contours.

The unique geometry of the 440 428-2 makes it perfect for applications such as radio base station and wireless network antennas. In these applications, the gasket creates a strong electrical bond between the flange and the chassis, where it is installed, and it provides a superior shield of radio frequency and electromagnetic interference. It is also suitable for RF/EMI shielding applications in communication equipment and consumer products.

When used in applications such as those mentioned above, the 440 428-2 gasket is responsible for the transmission line characteristic impedance, return loss and resonance point all being within the acceptable limits. This ensures that the impact of external sources of interference, such as electrical fields, EMI and other radio signals are kept to a minimum. This, in turn, allows for high data rates and reliable communications.

In terms of its working principle, the 440 428-2 relies on its flexibility and conductivity. This allows the gasket to maintain a continuous electrical connection between the mating parts and the shield that covers them. This is achieved by pressing the gasket into the mated components with a certain amount of force and then sealing them with adhesive to ensure a tight fit. The gasket then performs the function of maintaining a tight shield between the mated parts, providing superior electrical continuity.

The 440 428-2 is a versatile and reliable contact, fingerstock and gasket for all types of RF and EMI shielding applications. It provides superior performance and reliability in both commercial and industrial applications, allowing users to enjoy the benefits of reliable shielding for their communication systems and consumer devices. Thanks to its flexibility and conductivity, the gasket ensures a reliable, lasting shield between mated parts, making it a great choice for any EMI and RF shielding project.
