The MLX90367KGO-ABV-000-RE sensor is a contactless magnetic field sensor used to measure linear and angular position. Its main applications are geared towards servo motor and mechatronic valve control. In this article, we will discuss the MLX90367KGO-ABV-000-RE application field and working principle in detail.

Applications Fields

The MLX90367KGO-ABV-000-RE sensor is ideal for precision motion control in approaches such as stepper motors, rotating filing tables, aircraft autonation systems and motion profilers. It can be used to measure the position of harmonic drives and other high-volume applications where fast response times are required. Additionally, its 40 mm range and 0.1 degree accuracy allows it to be used in critical robotics applications such as robotic arms, pipetting systems, and precision machining. Additionally, its contactless design makes it ideal for applications in harsh environments like factories and industrial processes.

Working Principle

The MLX90367KGO-ABV-000-RE sensor uses a three-axis piezoresistive magnetoresistive (MR) technology to measure angular and linear position. Its functioning is based on the fact that a magnetic field is created when two permanent magnets are placed together. The MR sensor measures magnetic field strength in three patterns, or axes. The strength of the magnetic field is then used to calculate the angular or linear position. The MLX90367KGO-ABV-000-RE sensor is designed to measure up to 40mm in linear movement or 0.1 degrees in angular movement.

The MR sensor uses an ASIC (Application Specific Integrated Circuit) to measure the strength of the magnetic field. The ASIC contains a Hall effect sensor to measure the field and a bridge to preamp the signal. The preamp is required as the signal is weak and noise can easily corrupt the signal. The ASIC then digitizes the signal and passes it to the main ASIC for further processing.

The main ASIC is responsible for all the calculations and processing of the data. It takes the signal from the preamp and compares it to a reference point. Based on the difference between the two points, it can calculate the angular or linear position. The main ASIC also performs analog-to-digital conversion, temperature compensation, and other functions. Finally, the data is then output to an I2C bus, where it can be used by the rest of the system.

Conclusion

The MLX90367KGO-ABV-000-RE sensor is a contactless magnetic field sensor used to measure linear and angular position. It can be used to measure the position of harmonic drives and other high-volume applications with fast response times.
