Safe and reliable detection

DTECT® Presence Reflect: Photoelectric retro-reflective sensors

Photoelectric retro-reflective sensors from SensoPart enable simple object detection in automated production environments. When combined with a reflector, the light barriers deliver precise results even with challenging objects such as shiny, black, or transparent materials. With the benefits of red light and infrared technology and optional teach-in functions, our light barriers produce stable measurement results even in changing illumination conditions and with transparent objects – ideal for detection processes that require a compact solution with minimal adjustment effort.

Rely on the light barriers from our DTECT® series and optimize your object detection with the best in reliability. 

About reflective light barriers


DTECT Presence Reflect

Optimize your production facilities with photoelectric retro-reflective sensors from SensoPart

The proven technology of our sensors makes them especially easy to install: The emitter and receiver are enclosed in a compact housing, and the light is reflected back via an additional reflector. This allows the safety your light barrier provides to be integrated into a wide variety of applications with no need for fine adjustments during installation.

Our photoelectric retro-reflective sensors are ideally suited for challenging applications and reliably detect even objects with shiny, dark, or transparent surfaces. For maximum flexibility, our light barriers also feature various adjustment options – from potentiometers and teach-in to external control lines. For non-critical objects, they can even be used without any application-specific adjustments.  In addition, special autocollimation devices are available which, thanks to their design and special functions such as automatic background tracking (DELTA function), enable particularly reliable transparency detection and operation without a blind zone. 
 

Light barriers with IO-Link mode can be integrated effortlessly into existing systems and put into operation with little effort. Thanks to a selection of various different light sources – including laser, LED, and infrared – our light barriers can be optimally adapted to different applications and ambient conditions.

The advantages at a glance

  • Reliable object detection: precision detection, even with challenging objects
  • Easy installation: quick commissioning and, if needed, flexible light barrier parameter configuration
  • Flexible adaptation: different light sources for optimal adaptation to various applications
  • Robust design: light barrier with tightly sealed housing for reliable protection against dust, water, and cleaning solutions
  • Advanced special functions: unique autocollimation devices with background tracking (DELTA function) for transparency detection are available

Possible areas of application for DTECT® Presence Reflect photoelectric retro-reflective sensors

With a laser, LED, or infrared photoelectric retro-reflective sensor from SensoPart, you get the premium solution for a wide range of sectors and applications:

Detection of objects on conveyor belts

Detection of packages on conveyor belts

Application example Detecting transparent bottles in labeling processes

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

Perhaps a photoelectric retro-reflective sensor 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 through-beam sensor, a photoelectric diffuse sensor with background suppression, 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.
