High-End Hall Sensor Overview
3D Hall Sensor HE444:
High End Measuring Technology, Test Engineering, Quality Control,
NMR, MRI, MQR, ESR, Military
The 3D Hall Sensor HE444 was developed for military- and high end industry applications.
The 3D Hall sensor HE444 makes new applications possible. The sensor can measure strong magnetic fields, and also gives the 3D direction of the magnetic field. NMR sensors can also measure strong magnetic fields, but do not show the direction of the magnetic field.
No matter if you need field strength measurements in micro Tesla range, or want to measure field strengths of 5 Tesla, the sensor covers the complete measurement range at highest temperature stability with one single sensor. The cubical body is made of ceramics and has a side length of 3.3 mm.
The solder contacts are designed in QFN style to make the soldering points accessible. The contacts can also be bonded. Our technology leads to the worldwide best results regarding temperature and drift behaviour.
Our Hall sensors (1 dimensional) HE244 and (3 dimensional) HE444 reach new, until now unreached dimensions regarding precision and range.
Measurements by CERN Switzerland:
The PHE Error (Planar Hall Effect Error) is about 2 x E-5 = 20 PPM = 0.002%. This means we have 3 axes available, x, y and z, which are nearly 100% independent of each other. The measurements have been done by CERN Switzerland.
For qualitative validation of the 3D Hall sensors HE444, you can also use the datasheet and the diagrams of the HE244 sensor. The internal connections and the data are identical, in the 3D Hall sensor HE444 the same element is 3 times present. This means you can also indirectly test the 3D Hall sensor HE444 1 dimensional with the HE244.
Availability:
The 3D Hall Sensor HE444 will be available in January 2012 in SMD and twisted pair version.

1D Hall Sensor HE244:
High End Measuring Technology, Test Engineering, Quality Control,
Sensor Technology, Military
The 1D Hall sensor HE244 was developed for military- and industrial high end applications. The sensor has a very low offset and a very small offset drift.
See this link with measurements: diagrams HE244 Hall sensor. This document contains graphic charts for linearity, temperature coefficient, offset drift, offset voltage and frequency response. These measurements have been done by Projekt Elektronik in Berlin.
As you can easily see on the diagrams, nearly all important parameters of the HE244 are much better than the values of all other on the market available Hall sensors.
Here are the most important parameters from the measurement diagrams HE244 (also valid for HE444)

General information about HE144, HE244, HE444 Hall Sensors
- We only produce in Europe
- Small packages with low inductance and low EMC pickup, also LF
- The sensors have a current input and differential (balanced) voltage output
- The sensors measure positive and negative magnetic fields
- Customer specific packages can be created
- Integrating temperature sensing and/or current source and/or amplification is possible
- It is possible to use the sensors outside several specifications without destroying them
- Samples are available
- For dynamic low noise measurements , we recommend sensor currents of 1 mA for the HE144, 2 mA for the HE244, 2 mA for the HE244, 2mA per axis for the 3D hall sensor HE444
- For higher output, higher currents can be used, for example 5 mA for the HE144 and 10 mA for the HE244, 10mA per axis for the HE444
