Non Contact Angle Position Sensors
The rotational angle of a shaft, drum or other rotating object can be tracked by pairing an Angular Position Sensor with a specially magnetized target magnet. The magnet is mounted centered over the center of rotation and then the sensor is centered in front of the magnet.
Hall Sensors for Measuring Rotation Angle
Hall Effect Sensors and Magnets to Measure Rotation Angle (APS)

Analog Output Proportional to the Angle of the Magnet
Angular Position Sensors provide an analog output that is dependent on the rotational angle of the target magnet over 360 degrees or a smaller arc of movement.
- Sensor output is “typically” 10% to 90% of 5 Volts
- Regulated sensors are available to handle voltage input over 5 Volts
- Sensing angle can be custom programmed to the application range or a standard 90°, 180°, 270°, 360° factory programmed range
- PWM and other output protocols available
The angle of the magnetic field is resolved using a Hall effect sine and cosine output and an internal microprocessor. The output is a digital to analog converter that produces resolution of 0.36 degrees.
Angle Position Magnets
Angular position sensors track specially magnetized magnets to produce a usable analog output. The size and grade of the magnet will determine the operate gap range the sensor will work at. The operate gap for the magnet is defined in the sensor specifications sheet.
Angle Position Sensor Magnets are available as raw discs for the smallest mounting profile and in small flange mount packages with reference angles marked for easiest installation.
If you do not find the Angle Position Sensor you need in our catalog, contact our Engineers to discuss a custom solution including options for measuring only a portion of the rotation for increased resolution.
