Overview

  • Detects clear or transparent material and color variations
  • Senses within a 50 to 500 mm window with a 15 millisecond response time
  • Offers wide operating range of -20° to 60° C
  • Compensates for variations in air temperature
  • Delivers high accuracy in wet or dirty environments
  • Available in encapsulated models rated IP67 or IP68 for a range of harsh conditions
  • Offers 10 to 30V dc supply voltage with NPN or PNP output, depending on model
  • Features push-button TEACH for easy programming at the sensor or remotely
  • Includes bright LED operating status indicators visible from 360°
