Description
SMA Bulkhead Connector | Screw-Lock | Brass Body
The ROSNOL SMA2FB50-1730B/91 is a straight bulkhead jack connector featuring a screw-lock coupling mechanism and solder cup terminal for secure and reliable RF connections. Operating from DC to 18 GHz with a maximum VSWR of 1.25, this 50-ohm connector ensures high signal integrity and low insertion loss. Its solder attachment and bulkhead mounting style make it ideal for panel-mounted RF systems.Constructed with a brass body, fastening nut, and washer, each component is plated with 3 µinch gold over 80 µinch non-magnetic nickel-phosphorus underplating for optimal conductivity and corrosion resistance. The center contact is made of beryllium copper with identical plating, and the insulator is made of PTFE for stable dielectric 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.
