R2 Contact Gasket for Low Compression EMI Shielding Applications
The R2 Contact Gasket is a low-profile electrical contact designed for EMI shielding, grounding, and electrical continuity in compact electronic assemblies. Manufactured from beryllium copper, it provides reliable conductivity while requiring minimal compression force. As a result, it is an excellent choice for applications with limited closure pressure.
R2 Contact Gaskets are commonly used in telecommunications equipment, aerospace electronics, military systems, medical devices, and industrial enclosures. In addition, the low-profile design helps maintain continuous electrical contact between conductive surfaces. Therefore, it supports effective shielding while reducing stress on doors, panels, and enclosure components.
Engineers often select R2 Contact Gaskets for small openings and compact shielding applications. Furthermore, the spring-contact geometry accommodates dimensional changes and helps maintain reliable electrical performance over time. Consequently, these gaskets provide dependable grounding and EMI protection in space-constrained environments.
Leader Tech R2 Contact Gaskets are available in multiple lengths and plating options. As a result, designers can choose a configuration that meets specific shielding and grounding requirements. Moreover, the durable design supports long service life in demanding electronic systems.
