Application notes:


An easy way to do Hall sensor measurements


Offset compensation

The HE144P pin version can be used as pin-to-pin replacement for Siemens / Infineon KSY14 and KSY44 Hall sensors.

(RoHS and REACH compatible)


  • Wide range from a milli-Tesla up to 10 Tesla and above
  • Measures both positive and negative fields with high precision
  • Very low noise
  • Very wide temperature range; a high temperature version up to +250°C/+480°F is also available
  • Low temperature coefficient
  • Low temperature coefficient on offset
  • 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
  • XRay resistant


For dynamic, low noise measurements, we recommend sensor currents of 1 mA or lower for each channel of the HE144. For higher output, sensor currents up to 5 mA can be used.

As a rule of thumb, the HE144 series gives an output of 0,2 V/T at 1 mA sensor current.
