The ROSNOL SMA2GFD50-1200A/91 is a high-performance RF connector designed for secure panel mounting in microwave systems. It offers 50 Ω impedance and operates from DC to 18 GHz with VSWR ≤ 1.30, ensuring stable signal integrity. The screw-lock coupling mechanism supports ≥500 mating cycles for long-term reliability. Key dimensions include an overall length of 12 mm \[.472 in], flange size of 12.7 mm \[.500 in], mounting holes of Ø2.6 mm \[.102 in], and hole spacing of 8.64 mm \[.340 in]. The thread specification is 1/4-36 UNS, and the connector withstands temperatures from -65°C to +165°C.The center contact is beryllium copper with gold plating over a nickel-phosphorus underplate for superior conductivity, while the body is brass with the same plating for corrosion resistance. The insulator is PTFE, providing excellent dielectric properties. The flat terminal ensures secure electrical connection and mechanical stability under high-frequency conditions.
ROSNOL’s precision-engineered solutions offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment. Customization services for materials, plating, and mechanical design are available to support specialized requirements across a wide range of RF and microwave applications.
