Simply put, sensors are the eyes and ears of industrial automation. Regardless of the application, automation is simply not possible in today’s manufacturing process without sensors. There are many ...

What's behind the target can make a tremendous difference in how well reflective sensors do their job. Consider a photoelectric sensor operating in simple diffused mode (i.e., as a proximity sensor).

A typical reflective object sensor consists of an infrared light emitter diode (IRED) and an NPN silicon phototransistor mounted side-by-side on parallel axes in a compact black plastic housing. The ...
