Pneumatic Cylinder Sensors - How They Work |

A hall effect sensor is a magnetic proximity sensor that is switched “ON” when a radially aligned magnetic field is applied to it. A radially aligned magnet will produce a magnetic field perpendicular to the magnetic field of the hall effect sensor as seen in Figure 5. Unlike reed switches, hall effect sensors are solid-state devices and designed with different components. Reed switches ...
