Description
SMA Plug (Male) to 2.92mm Jack (Female) Adapter | Screw-lock | Stainless Steel Body
The ROSNOL AD-A1K25A/9XX-9X is a precision RF adapter supporting DC to 18 GHz. It delivers 50 Ω impedance, VSWR ≤1.15 (≥23.13 dB), and insertion loss ≤0.05 × √F (GHz) dB. Mechanical features include screw-lock coupling, ≥500 mating cycles on both sides, axial captivation ≥10 N (SMA) and ≥20 N (2.92mm), and torque range of 0.8–1.1 Nm.This adapter is built with a passivated stainless steel body and coupling nut, beryllium copper center contacts with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating, and PTFE and PS insulators for stable dielectric 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.
