QT50R Series Collision Avoidance Radar Sensor


R-GAGE QT50R, an advanced radar-based sensor for close and long-range presence detection in a broad range of weather conditions, features frequency-modulated technology to accurately monitor or detect objects while resisting rain, wind, humidity, and extreme temperatures.


The QT50R uses Frequency Modulated Continuous Wave (FMCW) radar to reliably detect moving or stationary cars, trains, trucks, and cargo. The QT50R detects target objects up to 15 m away and ignores anything beyond the setpoint. The IP67-rated sensor operates at 24 GHz in the Industrial, Scientific, and Medical (ISM) telecommunication band, with no special licensing required.


  • Range up to 24 m for robust target detection of both moving and stationary objects
  • Analog or discrete outputs for both measurement and detection applications
  • Adjustable sensing field to ignore objects beyond a setpoint with one or two zones available 
  • Rugged IP67 housing ideal for harsh outdoor applications​
  • Unaffected by temperature changes, ambient light or weather conditions including wind, falling rain or snow, fog, or humidity ​
  • Easy setup and configuration of range, sensitivity, and output with simple DIP switches​
  • Sensor operates in Industrial, Scientific, and Medical (ISM) telecommunication band no special license required
