2025 Top 10 Hall Effect Sensor Suppliers in the world

Introduction to Hall Effect Sensor

A Hall effect sensor is a type of sensor that detects the presence and magnitude of a magnetic field. It operates based on the Hall effect, which was discovered by Edwin Hall in 1879. When a current - carrying conductor is placed in a magnetic field perpendicular to the current flow, a voltage is generated across the conductor, known as the Hall voltage. This voltage is proportional to the strength of the magnetic field, and Hall effect sensors use this principle to measure magnetic fields and convert them into electrical signals.

Hall effect sensors have a wide range of applications, including automotive (for speed sensing, position sensing in engines and transmissions), industrial (for proximity sensing, current sensing), consumer electronics (for detecting the opening and closing of laptop lids), and many other fields due to their high accuracy, reliability, and non - contact operation.
