Photoelectric Sensors

Banner offers the world's most complete line of photoelectric sensors - over 12,000. We supply sensors to virtually all the manufacturing companies in the Fortune 500. 

Photoelectric sensors, also known as photo eyes, emit a beam of light that is used to detect the presence or absence of items and equipment or changes in surface conditions. When the emitted light is interrupted or reflected by the object, the change in light patterns is measured by a receiver and the target object or surface is recognized. Photoelectric sensors are very common in industrial manufacturing fields such as material handling, packaging, food and beverage, medical, and many others.

Depending on the style selected, they can be used with or without a reflector, be self-contained, long-range, heavy-duty, or compact. There are many different housing and mounting options to offer a correct fit that meets the demands of each application. They perform a wide variety of tasks and some of them can even be used in harsh environments.
