HE444 Ultra Stable 3D Hall Sensor


- Measures strong and weak 3D magnetic fields with very high precision, enabling measurement of field strength and 3D direction
- Ratiometric, measures positive and negative fields with high precision
- All axes cross exactly in the same center point
- Only 3.3 by 3.3 by 3.3 mm size
- Ceramic enclosure
- Can be soldered but also be bonded
- For testing the HE244 can be used, each axis is identical, but the HE444 shows an even better PHE (Planar Hall Effect) reduction
- Solderpad pinout as three times the HE244 Hall sensor, can also be delivered with welded fine twisted pair cable, contact us for more information
- Has a very wide temperature range, and a version up to +250 ºC (+480 ºF) is available
- Very low offset, with ultra low temperature coefficient on offset, giving ultra low total drift
- Also ultra low long term drift
- Very low noise
- Very wide range from a µTesla range to many Tesla
- Extremely low PHE (Planar Hall Effect) Error, meaning Z field measurements show no X and Y field errors
- Axes do not influence each other
- Typical 500 Ohm and 0,2 Volt/Tesla at 2 mA per axis
- Moves 3D Hall measurements into the 6+ digit range!
