Photoelectric sensors
Wide spectrum of optical sensors for standard applications or special requirements
The eagle eyes among sensors
Photoelectric sensors reliably detect the presence of objects and check their shape, color, distance or thickness with high accuracy. Compared to inductive or capacitive proximity switches, optical sensors have a significantly higher detection range. 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!
Different surface characteristics, sizes and colors of the objects require different operating principles and designs of photoelectric sensors.
Our wide spectrum offers every light type, whether red light, infrared, blue light 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, assembly, installation and handling. We also offer reliable and rugged versions for harsh environmental conditions. For other special applications, we also offer our photoelectric mini-sensors, color sensors, light bands and contrast sensors.

Diffuse sensors
- Ideal for detecting contrast differences – dependent upon surface, color and material
- For diffuse sensors with background suppression: reliable object detection with different ranges, virtually independent of surface, color and material
- Cost-effective and easy to mount and align thanks to highly visible light beam
- Shorter ranges compared to retro-reflective and through-beam sensors
- Mounting includes only one electrical device
- Light scanners with blue light for perfect detection of objects that are difficult to recognize
Fork sensors
