Magnetic field amplitude measurement

Generating magnetic field amplitude variation as a linear function of the position

illustration: Magnetic field amplitude measurement  

MMT has developed a complete family of magnetic circuit to generate a magnetic field amplitude variation as a linear function of a permanent magnet position. In association with the most recent field amplitude measurement Hall ASIC, these magnetic structures ensure the following performances:

  • Non linearity below +/-1% of the stroke on the automotive -40°C to 150°C temperature range
  • Low sensitivity to production and application tolerances (off centering in all axes) as well as external disruption (magnetic field, magnetic particles...)
  • Programmable through the connector (gain, offset, temperature compensation)
  • Rotary stroke from 2° to 160°
  • Linear stroke from 1 mm
  • Custom features available on request
