The MK21P-1C90C-500W is a magnetic sensor module used for position, proximity, and speed detection. This versatile module is designed to be used in a wide variety of applications, from industrial automation to medical imaging devices. It is designed to detect magnetic fields with minimum circuit complexity and high accuracy.The MK21P-1C90C-500W is a Hall-effect based magnetic sensor, making use of anisotropic magnetoresistance (AMR) to measure the amount of magnetization in the surrounding environment. The module consists of two main parts: the sensing element and the signal conditioning circuit. The module can be configured to detect a variety of magnetic field sources, including permanent magnets, rotating magnets, stellar magnetic fields, and electromagnetic fields.The sensing element is typically a small magnetoresistive device， such as a Giant Magnetoimpedance (GMI) magnetic field sensor. The GMI sensor is composed of a multi-finger magnetoresistive element and a bias magnet, which is placed at one end of the multi-finger element. When a field is applied to the sensor, the bias magnet induces a giant magnetoimpedance effect in the sensor, allowing for a high-level signal with minimal circuit complexity.The signal conditioning circuit is designed to amplify the output signal from the GMI magnetic field sensor and provide a voltage output to the application. The circuit includes an operational amplifier and passive filters, as well as precision reference voltage sources for the GMI sensor’s bias magnet calibration. This provides the necessary signal amplification and filtering for reliable and accurate position, proximity, and speed detection.The MK21P-1C90C-500W module is suitable for a wide range of applications in industrial, automotive, medical, and consumer industries. It can be used to detect vibration, speed, acceleration, tilt, and attitude in industrial automation, and as an optimizer in medical imaging devices. The module can also be used in cars to detect pressure, rpm, and gear shift positions in order to optimize fuel efficiency. Finally, the MK21P-1C90C-500W can be used to detect position, proximity, and speed in consumer applications such as remote controlled toys and wearable devices. Overall, the MK21P-1C90C-500W is an excellent choice for a wide variety of applications, providing reliable and accurate magnetic field detection with minimal circuit complexity. Its versatile design and wide range of applications make it an excellent choice for any designer looking to quickly and accurately detect position, proximity, or speed.
