Marking Side
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.
