Magnetic sensors, also known as magnetic switches, play a important role in the development of modern technology. Magnetic sensors are devices that use the magnetic field generated by an object to detect physical movements. AD521-02E is a high-performance magnetic sensor specially designed for DC motor applications. It is widely used to detect rotational positions, angular displacement and speed and is particularly suitable for automotive transmission applications.

The AD521-02E device incorporates a Hall effect based IC with integrated power MOSFET drive. It is designed to detect the position, angular displacement and speed of a DC motor by sensing the magnetic field generated by its rotor. The device features analog, digital and PWM outputs which can be used to accurately control the position, angular displacement and speed of the DC motor.

The AD521-02E sensor has a built-in magnetic flux concentrator, making it ideal for operation in a wide range of environments. The sensor can operate in temperatures ranging from -40°C to +125°C and its output is temperature compensated over the entire range. The device has a fast response time of less than 10us and a high sensitivity of 11mV/G. Furthermore, it is RoHS compliant and specifically designed for automotive applications.

The working principle of the AD521-02E sensor is based on the Hall effect. When a magnetic field is present, a voltage is induced across the Hall sensor. This voltage is then amplified by an integrated circuit (IC) and then converted into a digital signal. This signal is then used to control the position, angular displacement or speed of the DC motor. The device has a built-in hysteresis which helps to reduce the influence of unwanted fluctuations in the circuit.

The AD521-02E is a highly accurate and versatile magnetic sensor that can be used in a wide range of applications. It is an ideal solution for DC motor applications such as automotive transmission systems, robotics, motion control systems and industrial automation applications. It provides an accurate and cost-effective solution for position, angular displacement and speed sensing applications.
