Hall EffectBipolar LatchSensor

The HAL1881UA is a high-sensitivity bipolar latching Hall effect sensor designed for robust speed and position sensing in automotive and industrial environments.

Best for

  • Brushless DC motor commutation
  • Rotational speed sensing
  • Position detection

Avoid if

  • Non-latching switch behavior is required

Check before use

  • Magnetic field orientation (must be perpendicular to the package surface)
