Photoelectric Sensors commonly used
A photoelectric sensor is an optical control device that operates by detecting a visible or invisible beam of light, and responding to a change in the received light intensity.
Proximity sensors commonly found in motor control circuits
Proximity sensors detect the presence of an object (usually called the target) without physical contact. Detection of the presence of solids such as metal, glass, and plastics, as well as…
