> > WORLD-BEAM QS18 Series Clear Object Detection Sensors

Overview

The QS18 Series Clear Object Detection Sensor features a polarized coaxial optical design to ensure reliable detection of transparent, translucent, and opaque targets.

  • Reliably detects clear, translucent, or opaque objects — including PET, glass containers, and transparent films
  • Coaxial optics enable reliable detection of targets to the face of the sensor with no dead zone
  • "Clear Tracking" algorithm automatically compensates for the effects of dust and ambient temperature changes, enhancing sensor reliability and longevity
  • Fast response speed with low jitter for high speed bottling and packaging applications
  • Bright, visible red light spot makes alignment easy
  • 3 user-selectable thresholds optimize performance to the type of object being detected
  • Easy configuration of sensor by remote teach input or tactile push button
  • Convenient mounting options available for 18 mm barrel or side mount
  • Bright indicator LEDs show operating status from 360?
  • IP67 rated ABS housing
  • Dedicated PNP or NPN output with matching remote input wire
