Sensor for precision distance detection

DTECT® Presence Background: Photoelectric diffuse sensors with background suppression

For standard object detection tasks in production environments, photoelectric diffuse sensors with background suppression (BGS) are the right choice. Objects are detected based on their distance from the sensor. These sensors only detect what is relevant for your process – and deliberately ignore the background. This makes them ideal for automated processes with changing illumination conditions, changing objects, and limited space.

Discover why photoelectric diffuse sensors with BGS from our DTECT® series are the first choice for demanding detection tasks. 

About our reflective light sensors with HGA


DTECT Presence Background

Greater detection accuracy thanks to photoelectric diffuse sensors with BGS

Thanks to their precisely definable detection ranges, photoelectric diffuse sensors with BGS demonstrate their strengths especially wherever it is not possible to install a light barrier.

Thanks to our proven BlueLight technology, the photoelectric diffuse sensors work accurately and reliably even on dark surfaces and under challenging conditions. In Detect-All mode, compensation for reflective backgrounds provides additional reliability.

Advantages of photoelectric diffuse sensors with BGS at a glance

  • Accurate: Precision object detection even with difficult illumination and background conditions
  • Reliable: Unerring detection of dark, transparent, and shiny objects
  • Consistent: Prevents incorrect switching through targeted background suppression
  • Uncomplicated: Easy installation with no reflector or tedious alignment
  • Innovative with BlueLight: For increased interference immunity and detection accuracy

Comparing photoelectric diffuse sensors and light barriers: Find the optimal solution 

Perhaps a photoelectric diffuse sensor with background suppression is actually not the best choice for your application. Factors such as distance and surface properties, as well as environmental and mounting conditions determine which sensor principle will deliver the most accurate result. Whether it's a photoelectric retro-reflective sensor, a photoelectric through-beam sensor, or a photoelectric diffuse sensor – even small technical details in the design and functionality can make the decisive difference during operation. 
Our overview of the various sensor principles shows you at a glance which one best suits your needs.
