OH4N Unipolar Hall Effect IC (N pole)

General DeSCRJPTion:

Part No.: OH4N  Operate temperature: -40～150℃  Package:3000pcs/Reel

OH4N unipolar hall IC includes an on-chip Hall voltage generator for magnetic sensing, an amplifier that amplifies the Hall voltage, a schmitt trigger to provide switching hysteresis for noise rejection, and an open-collector output. It detects the changes of Magnetic field (N pole) and output a digital voltage signal. With the typical feature of wide range of working Voltage, operate temperature and high load capacity, OH4N performs well in many applications, such as POSTTTION control, speed detection and flow detection as a non-contact magnetic sensor.
