Description
SMA Jack (Female) | Coaxial End | 4-Hole Flange Mount | Brass Body
The ROSNOL SMA2GFA50-2950B/91 is a straight panel receptacle jack designed for high-frequency RF and microwave systems. It offers 50 Ω impedance and operates from DC to 18 GHz with VSWR ≤ 1.20, ensuring excellent signal integrity. The screw-lock coupling mechanism provides secure engagement and supports long-term reliability. Key dimensions include an overall length of 29.5 mm \[1.161 in], flange diameter of 12.7 mm \[.500 in], mounting holes of Ø1.7 mm \[.067 in], and hole spacing of 6.35 mm \[.250 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 underplate, while the body is brass with gold plating for corrosion resistance. The insulator is PTFE, offering superior dielectric performance. This robust construction ensures mechanical strength and electrical reliability under demanding 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.
