R-GAGE QT50R-AFS Adjustable Field, Short Range Sensors


Short-range radar sensor for high-volume car parking and other vehicle detection applications.

  • Fourth generation Frequency Modulated Continuous Wave (FMCW) radar detects moving and stationary objects
  • High sensitivity, short range
  • Adjustable sensing field—ignores objects beyond setpoint
  • Easy setup and configuration of range, sensitivity, and output with simple DIP switches
  • Sensing functions are unaffected by wind, falling rain or snow, fog, humidity, air temperatures, or light
  • Sensor operates in Industrial, Scientific, and Medical (ISM) telecommunication band; no special license required
  • Rugged IP67 housing withstands harsh environments
