  • Object detection independent of material color and ambient lighting − even transparent foils, glass, liquids and bottles are detected
  • Immune to dirt, dust, and fog
  • Available with one or two PNP/NPN switching outputs or an analog output (voltage or current)
  • Teach-in via Multi-Function input
  • Your benefits

  • Easy machine integration with standard M18 housing
  • Reliable operation in rough conditions ensures high machine availability
  • Synchronization mode enables area detection, which improves application flexibility and increases productivity
  • Unintentional adjustments to sensor settings are eliminated since teach-in process is done with an external wire
  • Integrated temperature compensation ensures high measurement accuracy
