Working Principle

The MLX90365LGO-ABD-000-SP utilizes a unique position sensor technology known as Hall Effect. Hall Effect is an electromechanical phenomenon in which a voltage is developed across a conductor when subjected to a magnetic field perpendicular to the conductor. This technology is used to detect and measure the position and speed of rotating objects.

The MLX90365LGO-ABD-000-SP consists of two main components: the feature detection module and the signal conditioning module. The feature detection module comprises of a set of Hall sensors that detect the features in the field, such as the north and south poles of the magnet, and the signal conditioning module uses an integrated amplifier to process the voltages. Together these components create a unique electrical signature which represents the angular position or linear position of the sensed object.

Conclusion

The MLX90365LGO-ABD-000-SP is an excellent position-measurement device capable of delivering precise measurements of angle, linear position, linear speed and acceleration. Its superior noise immunity, precision and low power consumption make it ideal for operation in harsh conditions and battery-powered applications. Its unique Hall Effect technology makes it possible to accurately measure the position and speed of rotating objects, making it a valuable tool in a wide range of industrial, automotive, consumer and healthcare applications.
