SINGLE HALL EFFECT SWITCH
Application Information

V
will turn on (low) if the S magnetic flux larger than the operation point (B
), and turns off whenever the magnetic flux is removed and
lower than the release point (B
rp
). The related waveforms are shown in Fig.3.

and Magnetic Flux Variety
The major applications are for contactless switching and shown as follows:
VCD/DVD loader, CD/DVD ROM: Detect if the tray is opened or closed.
Cover detector (open/close): Cellular phone cover detector, refrigerator door detector, microwave oven door sensor, etc.
Home safety: instead of reed relay to detect the situation of door/window.
Due to contactless and without mechanical contact point, its reliability and life cycle are much longer than reed relay. In
addition, its switching speed is much faster than mechanical devices.
