Photoelectric sensors

The new home of sensing range

Your Benefits

  • Reliable object detection at high sensing ranges and large detection angles, e.g., even with shiny or jet-black surfaces
  • Highly visible light spot simplifies alignment of the red-light versions
  • Precise, simple adjustment with potentiometer, teach-in button, or display
  • Laser class 1 and therefore eye-safe
  • High levels of availability and durability. Rugged even when subjected to high mechanical loads thanks to VISTAL™ housing.
  • The world's smallest sensor housing ensures great flexibility when designing machines
  • IO-Link extends functionality


The new home of sensing range

The powerful PowerProx MultiTask photoelectric sensors offer all of the advantages of time-of-flight technology in the world's smallest sensor housing to date, giving maximum flexibility when designing machines. Objects being conveyed at high speed, small and flat objects, and jet-black or shiny objects can now be reliably detected at sensing ranges between 5 cm and 4 m. PowerProx also provides stable detection results over a large detection angle. The “Distance”, “Speed”, “Precision”, „Small“, „Mini“, „Micro“, and “WTT280L” versions are designed to be used in different applications. This means that PowerProx always offers perfect solution – for empty bay detection via rapid counting right through to use in handling and assembly.
