Description
SMA Jack (Female) | Solder End | 4-Hole Flange Mount | Brass Bod
The ROSNOL SMA2GFA50-2740A/91 is designed for high-frequency RF systems requiring robust panel mounting. It offers 50 Ω impedance and operates from DC to 18 GHz with VSWR ≤ 1.30, delivering reliable signal integrity. The screw-lock coupling mechanism supports ≥500 mating cycles for long-term durability. Key dimensions include an overall length of 27.4 mm \[1.079 in], flange size of 15 mm \[.591 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 operates in temperatures from -65°C to +165°C.The center contact is beryllium copper with gold plating over a nickel-phosphorus underplate, while the body is brass with the same plating for corrosion resistance. The insulator is PTFE, providing excellent dielectric performance. The soldered stub 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.
