Description
2.92mm Jack (Female) | Solder Attachment | 4 Hole Flange | Stainless steel Body
The ROSNOL K2GFA50-1390B/9X is a 2.92mm female coaxial connector with a 4-hole flange mount and stub terminal design. Featuring a compact hole spacing of 6.35mm (0.250 inch), it is ideal for space-constrained RF applications.Equipped with a screw-lock coupling mechanism, it supports a frequency range from DC to 40 GHz and delivers consistent performance with a maximum VSWR of 1.20 (≥ 20.83 dB Return Loss), minimizing signal loss and reflection.
The connector’s center contact is beryllium copper with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. The body is stainless steel with passivation, and the insulator is PPO/PPE. ROSNOL RF solutions are RoHS compliant and engineered for high-frequency reliability.
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.
