Speed Hall effect sensors are widely used for detecting rotational speed (RPM), wheel speed, and shaft position in automotive, industrial, and robotic systems. These sensors offer reliable and contactless measurement, making them ideal for high-speed, high-durability environments.
Applications of Speed Hall Effect Sensors
- Automotive wheel speed detection (hall effect wheel speed sensor)
- Electric motor RPM monitoring (hall effect rpm sensor)
- Rotational speed feedback in BLDC motors (hall effect rotational speed sensor)
- Industrial conveyor belt speed measurement
- Robotic joint movement sensing
How a Hall Effect Sensor Detects Speed
A speed Hall effect sensor detects changes in magnetic fields as a magnetized rotor spins past it. Each pulse corresponds to a change in position, which can be converted into rotational speed using microcontroller logic.
