Description
SMA Plug (Male) | Soldered Cable Entry | Screw-lock | Beryllium Copper Body
The ROSNOL SMA1E50-0141A/99X is a SMA plug (male) straight connector engineered for high-frequency 50 Ω RF cable assemblies operating from DC to 18 GHz. This connector employs a screw-lock coupling mechanism to ensure secure mechanical engagement and stable RF performance in precision measurement applications. A soldered cable entry combined with a soldered center contact provides reliable electrical continuity and consistent impedance control. With a VSWR of ≤ 1.20 and robust mechanical durability rated for at least 500 mating cycles, the connector is suitable for high-performance RF systems.The connector body and center contact are manufactured from beryllium copper with gold plating over a non-magnetic nickel-phosphorus underplating to achieve excellent conductivity and mechanical strength. The coupling nut is made from passivated stainless steel, while a PTFE insulator and silicone rubber gasket support stable dielectric properties and environmental sealing. The SMA1E50-0141A/99X is compatible with .141 cables including ROSNOL RSR-141, RSF-141, RSF-141-FEP, and RG402/U.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities and are fully RoHS and REACH compliant. Customization services for materials, plating, and mechanical design are available upon request.
