The AD122-00E Magnetic Sensors MSOP-8 RoHS manufactured by NVE is a surface mount optically focused Hall Effect switch with a small 8-pin MSOP-8 package. It uses a proprietary process to produce a smaller, lighter package with improved sensitivity. This device is used to sense the presence and direction of a magnetic field, and can be used in applications such as motor control, over-speed sensing, speed sensing, contactless switches, head-position sensing, and current sensing. It features an operating temperature range from -40°C to +85°C and a supply voltage of 4.5V to 24V.
