OH4N Unipolar Hall Effect IC (N pole)
General Description:
Part No.: OH4N Operate temperature: -40～150℃ Package:3000pcs/Reel
OH4N unipolar hall IC includesan on-chip Hall voltage generator for magnetic sensing, an amplifier thatamplifies
the Hall voltage, a schmitt trigger to provide switching hysteresisfor noise rejection, and an open-collector output. It detects the changes ofMagnetic field (N pole) and output a digital voltage signal. With the typicalfeature of wide range of working Voltage,
operate temperature and high loadcapacity, OH4N performs well in many applications, such as position control,speed detection and flow detection as a non-contact magnetic sensor.
