3 / 9 page KMY_KMZ Linear Magnetic Field Sensors SENSOR SOLUTIONS ///KMY_KMZ Rev 4 1/2016 Page 3 Auxiliary field strengths below Hx<1.5 kA/m are not recommended, as small disturbances may flip the magnetization domains. Sometimes, the magnetic conditions in the application may provide enough Hx bias field stabilization. MEAS Germany can provide advice for customer specific magnet arrangements. If a bias field Hx is not applied or Hx is less than 2.5 kA/m, the sensor may be used only in a limited field range Hy, depending on the present total bias field Hx,tot. In this case, it is strongly recommended to ‘premagnetize’ the sensor, i.e. align all magnetic domains consistently, prior to the measurement. Hx,tot is the sum of all acting magnetic fields in x direction at the sensor die. Do not use the sensor outside the safe operating area. Leaving the save operating area can destroy an existing premagnetization and therefore will lead to unreproducible sensor signals.
