High Precision Analog Hall Sensors

HE244 Hall Sensor Series


Air gap

Ferrite core

Hall Effect sensor

A common application is magnetic field measurements in thin airgaps

In the HE244 Hall sensor, the high resolution, combined with the ability to detect small changes in very strong magnetic fields, moves your measurements into the ppm range.


The HE244 hall sensor series is ultra-stable

  • Very wide range from a few µ-Tesla up to 10 Tesla and above
  • Measures both positive and negative fields with very high precision
  • Very low noise
  • Very wide temperature range; a high temperature version up to +250°C/+480°F is also available
  • Very low temperature coefficient
  • Very low offset
  • Ultra-low drift as well as long term drift
  • Ultra-low PHE (Planar Hall Effect) Error.

Z-field measurements show no X- and Y-field errors

  • X-ray resistant


For dynamic, low noise measurements, we recommend sensor currents of 2 mA or lower for the HE244. For higher output, sensor currents up to 10 mA can be used. As a rule of thumb, the HE244 series gives an output of 0,2 V/T at 2 mA sensor current.





Typical Applications:

  • Measuring precise homogenous fields
  • Precise current and power sensors
  • Measure both strongly magnetized metals and remanent magnetism with one sensor
  • Measurements in small metal, magnet and ferrite airgaps
  • Low DC current in strong AC currents, for example in windmills where only a limited DC current is allowed to be fed into the net
