SINGLE HALL EFFECT SWITCH

Application Information (Continued)

V_owill turn on (low) if the S magnetic flux larger than the operation point (B_op), 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.

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.
