Smartly Combined: 2 in 1 – Distance and Intensity Detection

The PNG//smart series 1P format reflex light barriers are impressively versatile thanks to their reliable detection method, which combines distance and intensity detection. By combining both principles, the sensors detect objects regardless of color, shape and surface. The reflex light barriers detect objects up to a distance of 1 m using red LED light. All they need for their function is a defined background, which removes the need for additional mounting of a reflector. The dynamic readjustment of the switching threshold automatically compensates for gradual contamination, which ensures a high level of operational reliability.

Product Highlights at a Glance

Flexible Use Thanks to Scanning and Through-Beam Principle

  •  Teach-in on static or moving reference background

  • Combined principle enables object detection up to 1 m 

     

Easy Detection without Reflector

  • Avoidance of system downtimes due to dirty or defective reflectors

  • Time and cost savings thanks to reflector-free installation

Process Stability Thanks to Dynamic Readjustment

  • Compensation of the sensor in the event of gradual changes in the background, such as contamination

  • High system availability, as no reteaching required 

Reflex light barriers detect transparent packaging

Reliable Object Detection

  • Reliable detection results for semi-transparent objects, such as packaging materials

  • Stable detection on reflective or glossy surfaces
