A magnetic position sensor measures or detects position through the magnetic field associated with a target.

## In plain English

### What does Magnetic position sensor mean?

A magnetic position sensor measures or detects position through the magnetic field associated with a target.

### A simple example

A mechanism can carry a magnet whose movement is detected without a conventional rubbing contact.

### What the drawings help you do

Show the moving magnet or magnetic target and the fixed sensor position. The circuit senses field conditions related to position; the mechanical arrangement determines what movement those readings represent. Label the target’s movement and the reported position quantity rather than assuming every magnetic sensor measures the same axis.

### Before using this reference

- Identify the magnetic target and sensor locations.
- Show the motion or position quantity being measured.
- Reference alignment, calibration and output requirements.

### Can the sensor report position without knowing the target geometry?

The magnet, spacing, alignment and selected sensing method determine the relationship between field and position. The complete mechanical and electrical arrangement is needed to interpret the output.

### Terms

- Target: The object or magnetic feature associated with the measured movement.
- Calibration: The relationship established between sensor response and the reported quantity.
