2025 Best 10 Hall Effect Sensor Factory in the world

Introduction to Hall Effect Sensor

A Hall effect sensor is a type of transducer that varies its output voltage in response to a magnetic field. It is based on the Hall effect, which was discovered by Edwin Hall in 1879. When a current - carrying conductor or semiconductor is placed in a magnetic field perpendicular to the current flow, a voltage difference (Hall voltage) is developed across the conductor or semiconductor.

Hall effect sensors are widely used in various industries due to their non - contact nature, high reliability, and long service life. They can be found in automotive applications (such as speed sensors, position sensors), industrial automation (detecting the position of moving parts), consumer electronics (for example, in smartphones to detect the opening and closing of flip covers), and many other fields.
