A linear magnetic scale with a sensor measures linear displacement, position, or movement using magnetic fields. Key components:
1. Magnetized Scale : A linear magnetized strip or grid attached to the moving object.
2. Sensor : A magnetic field detector, typically a Hall effect, giant magnetoresistive (GMR), or magnetic encoder sensor.
1. Incremental : Provide position change information.
2. Absolute : Provide exact position data.
3. Hybrid : Combine incremental and absolute measurement.
1. Machine Tools : CNC machines, lathes, grinders.
2. Robotics : Positioning, navigation.
3. Medical Devices : Imaging, patient positioning.
4. Automotive: Brake, throttle, steering systems.
5. Industrial Automation : Conveyors, elevators.
1. High Accuracy: ±1-10 μm resolution.
2. Reliability: Resistant to dust, moisture, vibrations.
