Pepperl+Fuchs Photoelectric Sensors
Our broad range of photoelectric sensors is aimed at all automation solutions where noncontact object detection can be utilized. The wide variety of different operating principles, models, sizes and specifications means that the best possible sensor can always be found for the relevant application and all conditions that occur in practice can be met. In automation, photoelectric sensors in general provide all the benefits of fast and noncontact detection. They essentially consist of an emitter and a receiver unit. If an object moves into the beam path, for example, the receiver responds to changes in the amount of light received within milliseconds and converts the optical signal emitted by the emitter into an electrical switching signal. The photoelectric sensors operate with visible red light, invisible infrared light or powerful laser light as required.
The color and material of the detected objects do not generally play a significant role and even objects with transparent or reflective surfaces can be detected reliably. Among standard sensors, a distinction is made between the three functional principles of thru-beam sensors, retroreflective sensors and diffuse mode sensors, depending on the function and the relative position.

Photoelectric sensors are a great choice for packaging, material handling, automotive, and many other applications. They use a light emitter, a light receiver, and a lens for detection. Photoelectric sensors are often the go-to sensor, when an inductive sensor does not fit the application. They are incredibly useful for detecting a variety of objects, but it is important to be aware of their limitations.

Multi-ray photoelectric sensors are similar to a basic photoelectric sensor, but with the addition of more light sources or light beams. Multi-ray simply means more than one light beam.
Is there a specific type or style of multi-ray photoelectric sensors? Just like the basic, single beam photoelectric sensor, multi-ray photoelectric sensors can come in a large variety of sensing modes and housing styles.
