Description
SMA Plug (Male) to FME Jack (Female) Adapter | Screw-lock | Copper-Tin-Zinc Alloy Body
The ROSNOL AD-A1E25A/144-94 is a straight SMA to FME adapter designed for RF systems up to 2.5 GHz. It offers 50 Ω impedance, insulation resistance ≥5 GΩ, and contact resistance ≤3 mΩ (SMA) and ≤10 mΩ (FME). Mechanical specifications include screw-lock coupling, ≥500 mating cycles on the SMA side and ≥300 on the FME side, axial captivation ≥27 N and ≥28 N, and torque rating up to 1.7 Nm and 2 Nm.Constructed with a copper-tin-zinc alloy body and coupling nut, the adapter features beryllium copper and brass center contacts with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating. PTFE insulators and silicone rubber gaskets ensure robust dielectric and sealing performance.
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.
