Description
SMA Bulkhead Connector | Screw-Lock | Brass Body
The ROSNOL SMA2FB50-1900A/91 is a straight bulkhead jack connector designed for RF applications up to 18 GHz. It features a screw-lock coupling mechanism and solder cup terminal, offering secure mating and consistent electrical performance. With a 50-ohm impedance and VSWR ≤ 1.25, this connector ensures low signal loss and high reliability in demanding environments.The connector is constructed with a brass body, fastening nut, and washer, all plated with 3 µinch gold over 80 µinch non-magnetic nickel-phosphorus underplating for enhanced conductivity and corrosion resistance. The center contact is made of beryllium copper with identical plating, and the insulator is made of PTFE for excellent dielectric stability.
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.
