Description
SMA Female | Screw-lock | Epoxy Captivation
The ROSNOL SMA2GFA50-3550A-EC/91 is a 50 Ω impedance RF connector with a 4-hole flange mount and 8.64 mm (.340 inch) hole spacing. It features a screw-lock coupling mechanism and a soldered beryllium copper center contact. The stub terminal is epoxy captivated, providing axial retention ≥ 27 N and radial retention ≥ 3 Ncm.The connector body is made of brass with gold plating (3 µinch) over non-magnetic nickel-phosphorus underplating (80 µinch). The center contact shares the same plating structure, and the insulator is made of PTFE for optimal RF 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.
