The 27 km long CERN LHC particle accelerator has a large number of super-conducting cryogenic magnets installed to control and focus the particle beams, Hall sensors can here be used for mapping of the magnetic field. Credit to CERN
The 3-dimensional HE444-series has 3 times the HE244 integrated in a very small ceramic package where all axes cross in the same center point. Axes do not influence each other and they are separately accessible without PHE-errors. The HE444 makes it possible to measure both magnetic field strength and 3D direction using one sensor.
Solderpad pinout as three times the HE244 Hall sensor. For testing, the HE244 can be used, each axis is identical, but the HE444 shows an even better PHE reduction.
For dynamic, low noise measurements, we recommend sensor currents of 2 mA or lower for each channel of the HE444. For higher output, sensor currents up to 10 mA can be used. As a rule of thumb, the HE444 series gives an output of 0,2 V/T at 2 mA sensor current.
The HE444 sensor is currently under redesign and will not be deliverable until further notice
