Description
2.92mm Jack (Female) | Solder Attachment | 4 Hole Flange | Stainless steel Body
The ROSNOL K2GFA50-1390C/9X is a 2.92mm female coaxial connector designed with a 4-hole flange mount and stub terminal. It features a hole spacing of 6.35mm (0.250 inch), offering compact integration for RF systems requiring precision and stability.This connector supports a screw-lock coupling mechanism and operates from DC to 40 GHz. With a VSWR ≤ 1.20 (≥ 20.83 dB Return Loss), it ensures high signal integrity and low reflection across RF applications.
Constructed with premium materials, the 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 components are RoHS compliant and built for long-term performance.
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.
