Each specification is defined by testing above items individually.
When shifting the sensor output from L to H, please make sure the magnetic field applied to the sensor
becomes higher than the above operating magnetic field (Hon) through your designing.
NOTE3) When shifting the sensor output from H to L, please make sure the magnetic field applied to the sensor
becomes lower than the above operating magnetic field (Hoff) through your designing.
NOTE4)
Sensitivity selection of this product is performed at Vcc=12V. Operating magnetic field can possibly
change when applying the supply voltage other than 12V. Please consult with us for technical assistance
when you consider the supply voltage other than 12V, as a special attention needs to be given in the
design.
