WORLD-BEAM: Polarized Retro

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.
