Low-power speed sensor

AMG049-003

  • Very low power consumption
  • High sensitivity and detection performance
  • No need to set-up stand-by cycle 
  • Well defined detection zone
DESCRIPTION

The AMG049-003 is ideal for measuring speed with minimal energy consumption. It is a compact, cost-effective and versatile Doppler sensor working in the 24 GHz frequency band which can be easily integrated into vehicle activated displays, traffic counting units or speed performance measuring systems.  

This reference is very well suited to both battery and solar-powered uses. Its unique radar signal processing design ensures outstanding detection performance and sensitivity at a very low current (13mA @ 12V), while also making unnecessary to program stand-by cycles to ensure low-power consumption throughout. 

Like all sensors in our catalogue, the AMG049-003 is available as OEM part or enclosed in a polycarbonate cover. 

  • 5 km/h to 200 km/h speed range
  • 35 ms sampling time
  • ± 1 km/h precision
  • 9 V to 30 V voltage
  • 13 mA typ. current
  • RS232, or RS485, or UART data interface
  • 3 TOR outputs
  • Approaching and bi-directional detection
  • Adjustable sensitivity by rotary switch. 
  • Programmable speed thresholds

Installation recommendations

This sensor should be installed at an angle, or a field of view to the road, of < 10° for speed measurements with less than 2% error. Installation at an angle of > 45° can result in speed measurements with low accuracy. 

The thinner the beamwidth is in the target moving plan, the more accurate the speed measurement is. Hence, to ensure accurate speed detection, place the wide side of the sensor horizontally for detection from the side of the road. For detection from above, place the wide side of the sensor vertically.
