The air gap is determined by the sensor's sensitivity (Bop/Brp) and the magnet's flux density. Consult the sensor datasheet for the minimum required field strength at the target distance.
Sensor-Matched Magnets Component Intelligence
Optimized magnetic flux for consistent sensor triggering
What are Sensor-Matched Magnets components?
Sensor-matched magnets are calibrated to provide the specific flux density and polarity required for reliable switching in reed, Hall effect, and GMR sensors. Selection depends on the sensor's sensitivity threshold, the required air gap, and operating temperature stability.
How to Choose Sensor-Matched Magnets Components
Selecting the correct magnet is as critical as the sensor itself. Focus on these technical parameters to ensure reliable switching.
Flux Density (Gauss)
Ensure the magnet provides sufficient field strength at the maximum operating air gap to trigger the sensor.
Material Stability
Choose between Neodymium (high strength), Ferrite (cost-effective), or Alnico (temperature stable) based on your thermal environment.
Polarity Orientation
Verify if your sensor requires axial or diametric magnetization to ensure correct polarity alignment.
Operating Temperature
Check the Curie temperature and thermal coefficient to prevent signal loss in high-heat applications.
Physical Packaging
Select housing types—such as threaded, surface mount, or encapsulated—that match your mechanical mounting constraints.
