With a new generation of optoelectronic sensors, Balluff offers a universally applicable and reliable solution for detecting objects and expands its globally established product family. These new sensors have compact and robust cubic standard housings and include all sensor principles – including photoelectric proximity switches with and without background suppression, retro-reflective sensors, and through-beam sensors. The sensors are available with both invisible infrared light and red light, which is highly visible and, thus, easy to align. 

The integrated wide beam version with its 100 mm range, as well as the smaller beam version with its 50...150 mm range, offer high flexibility. The same applies to their uncomplicated normally closed/normally open switching and potentiometer, which enables quick and easy sensitivity adjustment. 

Thanks to their versatile features, these new photoelectric sensors reliably and accurately detect a wide range of objects – regardless of shape, color or material. The field of application is diverse because of this color and material autonomy. Photoelectric proximity switches in the food and beverage industry can detect plastic bottles easily and reliably. Through-beam photoelectric sensors are often used to detect foodstuffs filled in cardboard packaging, such as breakfast cereals or noodles. Retro-reflective sensors can be used to detect small pallets of colored plastic that pass over a conveyor belt — ideal for factory automation, life science, metalworking, and the automotive sector. In the latter, through-beam sensors with long-range detection, can detect the car body before it is dipped in primer, for example, or small components, such as plastic trim, can be detected by a photoelectric proximity switch with background suppression.
