CarSense303

Magnetoresistive Vehicle Detector

  • Easy installation above or below ground
  • Ignores cross traffic in tight spaces with DETECT-ON-STOP™ feature
  • Quick setup with the ULTRAMETER™ sensitivity display
  • Logic Interface available for extended detection range

The CarSense 303 vehicle detector features advanced 3-axis, magnetoresistive sensing technology that responds to changes in the Earth’s magnetic field caused by ferrous objects. Three sensing elements provide measurements in the X, Y and Z axes to improve detection sensitivity when used in either above or below ground installations.

The CS303 is equipped with our new DETECT-ON-STOP™ or (DOS®) feature, which allows detection only when a vehicle has come to a complete stop. This exclusive feature is unique to EMX and is a major advantage if you want to ignore cross traffic in tight spaces.

The detector’s compact, loop-less design reduces installation costs when compared to traditional inductive loop technology.

  • Three-dimensional presence detection of vehicles
  • Select X,Y,Z axis independently
  • Stand-alone sensor
  • Sensor stores ambient background and settings in non-volatile memory
  • Remote control module for programming and additional relay contact output
  • ULTRAMETER™ displays optimum sensitivity setting/crosstalk interference
  • DETECT-ON-STOP™ allows detection only when a vehicle has come to a complete stop
