Diffuse sensors

Photoelectric sensors

Available in:

17 Series

Our vast array of diffuse sensors offers an economical solution if you want to reliably detect contrast differences. These diffuse sensors detect objects based on their surface, color, and material. Thus, their scanning range depends on the size, shape, color, and texture of the reflective object surface.

The transmitter and receiver are housed together in a single unit so that you can easily mount the diffuse photoelectric sensors and align them quickly using their highly visible light beams. You select the most suitable light type based on your application. Depending on the model, our diffuse sensors offer you highly visible red light, invisible infrared light, or very precise laser light that is ideally suited for detecting small parts.

For color-independent and surface-independent detection, we recommend diffuse sensors with background suppression. They work with red light or the laser red light that is ideally suited for detecting small parts. Their scanning behavior is virtually constant, even with different reflectance levels. Our diffuse sensors with background suppression detect objects within a set switching distance, without being affected by reflective backgrounds. Object and background can be differentiated very definitively, especially as these diffuse photoelectric sensors are characterized by their low gray value shift and hysteresis.

Since the transmitter and receiver are housed together in a single unit to save space, you can easily mount our background suppression photoelectric sensors and align them quickly. In addition, the highly visible light beam with the versions available in red light, blue light and lasers make it easier for you to do this. With IO-Link, teach-in or via potentiometer, you can easily adjust many sensor versions. Versions with fixed switching distance are also available.

Special features of our 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
