High-End Hall Sensor Overview

• 3 types available: the precise HE144 Hall sensor, the stable ánd precise HE244 and the 3D HE444
• Very precise Hall Effect Sensors, analog Hall sensor ICs
• Can also be used as RoHS replacements for the original Siemens / Infineon KSY14 and KSY44 or even KSY10 and KSY13 Hall sensor
• We use proven technologies with long-term reliability and stability
• Very high resolution, ppm level, can be used with modern magnets
• Optimized for low Hall sensor current, less power or battery consumption
• Measure strong magnetic fields with high precision, even tested above 10 Tesla
• Many digits (6+) due to the high resolution, combined with ability to detect small changes in very strong magnetic fields
• Wide temperature range. Already tested downto-196 degrees Celcius, -320 degrees Fahrenheit, a test to 4 Kelvin is in process
• Robust, can be used outside specifications and will still work
• Very low noise, ideal for magnetic measurements or controls
• A very low PHE, no error reading in X and Y direction, perfect for ratiometric 3D magnetic field measurements
• Moves your Hall sensing from % range to ppm range
• Special packages are possible, just ask, we are specialized in custom packages for all kinds of electronic components

General information

• We produce in Europe
• Small packages with low inductance and low EMC and magnetic loop pickup, also in lower frequencies
• The sensors have a current input and differential (balanced) voltage output
• The sensors measure positive ánd negative magnetic fields
• The sensors are optimized for low sensor currents
• 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, especially very low temperatures are no problem at all, the sensors are already tested in liquid nitrogen
• Samples are available
• For dynamic, low noise measurements , we recommend sensor currents of 1 mA or lower for the HE144, 2 mA or lower for the HE244, 2 mA or lower for each channel of the HE444
• For higher output, higher currents can be used, 5 mA for the HE144 and 10 mA for the HE244 and HE444
