Optoelectronic sensors

Impressive specialist sensors that check for presence, shape, colour, distance and thickness

Photoelectric sensors check presence, shape, colour, distance, and thickness - optimised for robotics, automation, assembly, and handling. They are real experts with various strengths: detecting and counting parts, monitoring stack heights, through-glass detection, aligning small parts, detecting marks, fill level detection, and much more!

The wide Balluff spectrum offers every light type, whether red light, infrared or laser technology, in different ranges. With and without background suppression. Various designs – also in mini version – ensure a wide variety of possible applications. Our photoelectric sensors are optimized for robotics, automation, installation and handling.
