HAL710 SF-E is a hi-tech magnetic sensor manufactured by STMicroelectronics. It is an open-loop Hall-effect linear position transducer with built-in intelligence and user customization capabilities.

HAL710 SF-E provides a reliable, versatile and affordable solution for a wide variety of applications requiring precise linear position sensing from low to high potentials. The sensor can be used in a variety of magnetic fields, from the very low frequency of the AC waveform of a phase reversal motor control system to high frequency applications such as a vehicle speed sensor. It is ideal for a number of applications including: motor control, valve and hydraulic actuator control, automotive engine control, automotive gearbox control, factory automation control, and robotics.

HAL710 SF-E has an integrated sensor interface and onboard microcontroller. This allows for precise measurement of linear position, even in fluctuating magnetic fields. The microcontroller is configured using a dedicated software tool, providing the user with the flexibility to customize the settings for their specific application requirements. The sensor is also capable of detecting a range of magnetic fields, from low to high frequency, up to 1 MHz.

The working principle of HAL710 SF-E is based on the use of Hall effect sensors. Hall effect sensors detect the presence and strength of a magnetic field by measuring the voltage generated in the vicinity of the sensor. As the linear position transducer moves, the Hall effect sensor detects the changes in the magnetic field and generates an output voltage. This output voltage is then processed and converted into linear position data, which is then sent to the microcontroller. Using this data, the microcontroller is able to precisely control the motor or valve/hydraulic component according to the user’s requirements.

HAL710 SF-E is a highly capable magnetic sensor, and its open-loop operation and user customization options make it an attractive solution for both industrial and consumer markets. Its ability to accurately measure linear position in a range of magnetic fields makes it perfect for applications in motor control, factory automation, robotics and automotive control.
