Compatible with common coaxial cable types listed in the electrical specifications when matched to the corresponding dielectric and working voltage requirements. Typical Use Scenarios Aerospace and Defense: Connect handheld field test instruments and onboard avionics for reliable RF measurements and signal routing in harsh environments. Telecommunications and Wireless Infrastructure: Interface with cellular base station equipment, antenna feeds, and backhaul test systems where low VSWR and stable impedance are critical. Industrial and Vehicle Systems: Use in vehicle tracking, M2M communications, Bluetooth and GPS modules, and instrumentation where temperature range and mechanical durability are required. What Makes This Connector Stand Out Designed for consistent electrical performance across the specified frequency band with clearly defined contact resistances and insulation parameters. Threaded coupling and defined torque/retention values ensure repeatable, secure connections in both fixed installations and field use. Material and finish choices support longevity and stable conductivity under cyclic use and environmental stress. Ordering Notes Available in straight and rightangle styles. Select the style that matches equipment layout and VSWR requirements. Verify cable compatibility (RG142, RG405, RG316, RG402, RG178) against the dielectric and working voltage values when specifying assemblies. This SMA connector is intended for precision RF and instrumentation applications requiring a robust, wellspecified 50 ohm interface.
