INTERFACING SENSING AND CONTROL HALL-EFFECT SENSORS
The schematics shown are typical of the outputs with which Honeywell Sensing and Control Hall-effect position sensors can be interfaced.
Values shown are representative only.
Current-Sinking outputs
Current flows through load into sensor. Output terminal is open collector. In the un-operated condition (I_L = 0), the output voltage is
normally high.
