Hall Sensor – Description

• A Hall sensor is an electronic device that detects the presence, strength, and direction of a magnetic field.

• It works on the Hall Effect principle, producing a voltage output when exposed to a magnetic field.

• Hall sensors allow contactless and wear-free sensing, making them highly reliable for automation, motors, robotics, and industrial systems.

• They are available in digital (ON/OFF) and analog (variable output) versions, suitable for precision detection task.

• Position detection for shafts, levers, and rotating parts.

• Proximity sensing for magnetic triggers in machines.

• Current sensing in power supply circuits.

• Safety switches in doors, lid detection, and magnetic locks.

• Robotics for encoder systems and motion tracking.

• Consumer electronics like smartphones, laptops, and gaming devices.
