  • Continuous threshold adaption of the switching threshold compensates for environmental changes
  • Single-lens autocollimation optics
  • Simple setting either via teach-in pushbutton, cable or IO-Link
  • PinPoint LED technology with a small, highly visible, well-defined light spot enables high reserve levels when using small reflectors
  • Flexible sensor settings, monitoring, advanced diagnostics, and visualization thanks to IO-Link
  • Your benefits

  • Optimal detection of any kind of transparent object
  • Quick and easy operation via the push of a button - automatic setting of the correct switching threshold
  • Less downtime due to a Continuous Threshold Adaption which compensates for changing environmental conditions, including temperature, dust and drift effects
  • The well-defined, highly visible intense light spot provides quick and reliable alignment
  • IO-Link provides easy data access from the PLC
  • Quick and easy configuration
  • Quick and easy integration using function blocks
  • Easy device replacement and identification
