Description
Non-Magnetic SMA Plug (Male) | Crimped Cable Entry | Screw-lock | Brass Body
The ROSNOL NM-SMA1C50-G058A/144 is a non-magnetic SMA plug (male) straight connector engineered for 50 Ω RF cable assemblies operating from DC to 5 GHz. This connector features a screw-lock coupling mechanism to ensure secure mating and stable RF performance in precision measurement and sensitive RF environments. A crimped cable entry with a center contact that can be soldered or crimped provides assembly flexibility while maintaining consistent impedance control. With a VSWR of ≤ 1.20 and low insertion loss characteristics, this connector is suitable for reliable RF signal transmission. Mechanical performance includes a recommended coupling torque of 0.57 Nm and a minimum mating life of 500 cycles.The connector body and coupling nut are manufactured from brass with a copper–tin–zinc alloy composition to provide mechanical strength while maintaining non-magnetic properties. The center contact features gold plating over a non-magnetic nickel-phosphorus underplating for low contact resistance and long-term electrical stability. A PTFE insulator and silicone rubber gasket support stable dielectric performance and environmental sealing. The NM-SMA1C50-G058A/144 is compatible with RG58, RG303, RG141, Times Microwave LMR 195, and ROSNOL RNL 195 cables.
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.
