Key Specifications
Description
2.92mm Plug (Male) Connector for .047 inch Cable, DC to 40GHz VSWR ≤ 1.2, 50 Ω, with soldered center contact and soldered cable entry.
The ROSNOL K1E50-0047A/99 is a high-performance 2.92mm Plug (Male) RF connector designed for reliable microwave signal transmission in demanding applications. Engineered for RSF047, RSF047 PVC, RSF047 FEP, and RSR047 cable types, this 50 ohm connector supports frequencies from DC to 40 GHz while maintaining a low VSWR of ≤1.20. Its compatibility with 2.92mm and SMA interfaces makes it a versatile solution for RF test systems, communications equipment, instrumentation, and high-frequency interconnect assemblies where signal integrity is critical.
Built with beryllium copper center and outer contacts, the connector features durable gold plating with a non-magnetic nickel-phosphorus underplating to enhance conductivity and corrosion resistance. A PTFE insulator supports stable electrical performance. Key specifications include insertion loss of ≤0.04 × √F (GHz) dB, insulation resistance ≥5 GΩ, center contact resistance ≤3.0 mΩ, and outer contact resistance ≤2.0 mΩ.
The K1E50-0047A/99 incorporates a secure screw-lock coupling mechanism and is rated for at least 500 mating cycles, providing dependable long-term operation. Its compact design and broad cable compatibility make it suitable for RF measurement systems, laboratory equipment, aerospace electronics, wireless infrastructure, and other high-frequency applications requiring consistent microwave connectivity.
