The CarSense™ 303 features advanced 3-axis magnetoresistive sensing technology.
The sensor measures Earth’s magnetic field and responds to disturbances caused by ferrous objects.
The CS303 combines this exciting new technology with a fieldproven hardware platform to produce a high-sensitivity compact and cost-effective solution for reliable vehicle detection.
Three sensing elements provide magnetic field measurement in the X Y and Z axes improving detection sensitivity.
