Hall Effect Sensors
Hall-effect sensors detect magnetic field changes to provide non-contact position sensing, current measurement, and speed/rotation detection. Used in automotive (throttle position, wheel speed), industrial (motor commutation, door detection), and consumer (lid switch, joystick) applications from Allegro, Honeywell, TDK, Infineon, and ams-OSRAM.

Hall-Effect Sensor ICs are specialized magnetic detection devices designed to detect the presence, strength, and polarity of a magnetic field using the Hall-voltage effect. Spanning digital Hall switches (which toggle output states when a magnet passes, ideal for open/close detection), latching Hall sensors (used for motor commutation and rotary encoding), and linear Hall sensors (providing a continuous analog output proportional to magnetic field strength), these devices are fundamental to non-contact industrial and automotive sensing.
Hall-effect sensors are widely used in throttle position sensing, wheel speed measurement (ABS), smart phone covers, and brushless motor commutation. Key selection specifications include magnetic operate point (BOP) and release point (BRP), output configuration (open-drain, push-pull, or analog), supply voltage range, current consumption (microamps), and package footprint (SOT-23, TO-92). Automotive models require AEC-Q100 qualifications.
