Limit Switches and Proximity Sensors 231

Limit Switches and Proximity Sensors introduces users to commonly used manufacturing sensors that detect the presence or absence of an object. Limit switches are mechanical sensors that require physical contact to be actuated. There are many variations of limit switches, including different operating mechanisms and environmental classifications. Proximity sensors, including inductive, capacitive, and Hall Effect sensors, do not require physical contact because they use an electronic or magnetic sensing field. These devices have different advantages and disadvantages and are used for various applications. Limit switches and proximity sensors are widely used for automated systems in all types of industries. They are used to control speed and motion as well as detect, count, position, and divert parts. After taking this class, users will understand the function, application, and installation considerations for commonly used limit switches and proximity sensors.
