Description
2.92mm Plug (Male) Panel Connector | Screw-lock | Stainless Steel Body
The ROSNOL K1GFA50-1990A/9XX is a 2.92mm Plug (Male) panel-mounted RF connector supporting broadband performance from DC to 40 GHz with a 50 Ω impedance. This model utilizes a 4-hole flange mount with a hole spacing of 8.64 mm (0.340 inch), providing mechanical stability for panel and chassis installations. Electrical performance includes VSWR ≤ 1.20 (Return Loss ≥ 20.83 dB), insertion loss ≤ 0.04 × √F (GHz) dB, and a maximum working voltage of 250 V rms, making it suitable for high-frequency RF equipment.Constructed with a passivated stainless steel body, this connector delivers long-term durability and resistance to environmental stress. The beryllium copper center contact with gold plating over a non-magnetic nickel-phosphorus underlayer ensures excellent conductivity and repeatable mating performance. A PEI insulator and silicone rubber gasket further contribute to stable RF characteristics and secure panel mounting with the 4-hole flange design.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
