Description
SMA Short | Plug (Male) | 50 Ohm
The ROSNOL SMA1AS50-1270A/933 is a precision RF test accessory designed to provide a defined short-circuit termination with a nominal impedance of 50 ohms. By directly shorting the center conductor to the outer conductor, this accessory establishes a known electrical reference condition for RF and microwave measurement systems. It features an SMA plug (male) configuration with a screw-lock coupling mechanism and supports operation from DC to 18 GHz. The component is specified for reliable performance across a temperature range of −65 °C to +165 °C.The ROSNOL SMA1AS50-1270A/933 is manufactured with a brass body and coupling nut finished in nickel plating, while the center contact is produced from beryllium copper with gold plating over a non-magnetic nickel-phosphorus underlayer. A PTFE insulator and silicone rubber gasket are incorporated to support mechanical alignment and material stability. Mechanical dimensions are provided in millimeters with inch references, and standard manufacturing tolerances are applied to ensure consistency across production units.
Produced under ISO 9001-certified quality systems, ROSNOL SMA Short accessories fully comply with RoHS and REACH directives. These precision RF test components deliver consistent and well-defined short-circuit reference states and serve as a cost-effective alternative to comparable products from leading global manufacturers. Customization services for materials, plating, and mechanical design are available upon request.
