RFI and EMI - Contacts, Fingerstock and Gaskets encompass a wide variety of applications including industrial, defense, aerospace, automotive, medical, telecom, and semiconductor. This article will discuss the application fields and working principles of the SG080160D-09.00 fingerstock and associated gaskets.

SG080160D-09.00 contact gaskets are highly specialized fingerstock components used in electromagnetic interference (EMI) and radio frequency interference (RFI) shielding applications. The fingerstock provides a reliable, uniform electrical connection with a companion fingerstock or contact surface and eliminates the need for conductive screw or gap/space bridges between the two ends. SG080160D-09.00 fingerstock and gasket designs afford excellent shielding effectiveness, even in harsh environmental conditions, and are widely used in all types of commercial and mil/aero applications.

The SG080160D-09.00 contact gaskets are designed to compatible with standard printed circuit board, component, and substrate copper or solder mask materials. The contacts are manufactured to exacting dimensional and electrical specifications using high quality materials such as phosphor bronze, beryllium copper, silver-plated copper, stainless steel, and tin-plated copper. The contacts are designed to provide the necessary crimp and solder connections for RFI/EMI shielding applications, as well as spring fingers, axial contacts, and other electrical connections.

The fingerstock and gasket are pre-molded for improved electrical performance and increased protection against EMI and RFI interference. The fingerstock performance depends on the shape, size, and material of the contact, as well as the load rating applied. The shield material is usually aluminum, but other materials such as stainless steel, copper, or tin-plated copper can be used. The contact design must also be optimized for the application to ensure optimal electrical performance.

The working principle of the SG080160D-09.00 contact gasket is relatively simple. The fingers of the fingerstock are crimped or soldered onto the mating surface and the gasket is placed over the fingerstock. The gasket acts as the electromagnetic shield, which blocks EMI/RFI signals from entering or leaving the device. The contact fingers are spring-loaded in the gasket, and the fingerstock is squeezed against the mating surface by the finger pressure, ensuring that the contact stays securely in place. In some applications, the fingerstock and gasket are glued, riveted, or crimped for additional stability.

The SG080160D-09.00 contact gaskets are mainly used for EMI/RFI shielding applications in defense, aerospace, automotive, medical, and telecom markets. In addition, they are used for signal integrity, high-speed connection, and thermal management solutions. The contact gaskets are also used in power supply and low-frequency signal applications to maximize signal isolation and minimize power consumption

In conclusion, SG080160D-09.00 contact gaskets and fingerstock provide excellent performance and reliability in EMI/RFI shielding applications. The fingerstock and gasket are designed to be compatible with standard PCB, component, and substrate materials, and optimized for the application to ensure optimal electrical performance. The fingerstock and gasket are pre-molded for improved electrical performance and enhanced protection against EMI and RFI interference.
