BU52077GWZ-E2 Application Field and Working Principle

BU52077GWZ-E2 is a magnetic sensor that belongs to the family of compass, magnetic field modules. It’s a Hall Effect magnetic field sensor usually used in Hall position control applications such as angle detection, positioning, and steering. This magnetic sensor from ROHM Semiconductor is highly accurate with temperature range between -40°C to +125°C and is highly reliable with an output of ±2.5%.

Application Fields

The BU52077GWZ-E2 is used in many different industries and applications, ranging from industrial automation to home appliances. A few examples include:

• Automotive: Motor Control, Position Sensor, Steering Wheel Angle Sensor and Direction Sensor
• Elevators: Position Sensor for Floor Carriage
• Robotics: Position Sensor, Angle Detection and Steering Sensor
• Home Appliances: Washing Machines, Refrigerators, Air Conditioners and Ventilators

The BU52077GWZ-E2 is also suitable for motor-control applications, since it has a high output linearity and temperature compensation accuracy.

Working Principle

The BU52077GWZ-E2 works on the principle of Hall Effect. Essentially, when a current is passed through a conductor placed in a magnetic field, an electric field is produced on its surface perpendicular to both the conductor and the magnetic field. This electric field is used to measure the amount of magnetic field at a given point, which in turn is used to detect the angle of the field.

In the BU52077GWZ-E2, there are two magnetic Hall effect elements adjacent to each other. The output of these two elements are then processed by a digital signal processor, which provides the output as a digital signal. By doing this, the BU52077GWZ-E2 is able to detect the angle of the field in a highly accurate manner.

The BU52077GWZ-E2 features a high output linearity, which helps to maintain accuracy over the entire operating temperature range. It also features an adjustable offset, which can be used to compensate for the offset of the sensor. The BU52077GWZ-E2 also has an adjustable gain, which can be used to adjust the output signal of the sensor.

Conclusion

The BU52077GWZ-E2 is a Hall Effect magnetic sensor that belongs to the family of compass, magnetic field modules. It’s used in many industrial and consumer applications to measure the angle of a magnetic field in a highly accurate manner. The sensor features a high output linearity, adjustable offset and adjustable gain, making it suitable for a wide range of applications.
