SICK WLL190T-2M492 Overview



Photoelectric fiber optic switch WLL190T-2M492 Base unit

SICK WLL190T-2M492 Description



  • Scanning range up to 4 m, scanning distance up to 480 mm
  • Two separately adjustable channels
  • Alarm output
  • Optional analog output
  • Integrated counter
  • Bus-compatible with anti-interference
  • 2 x 4-digit display
  • Red and green emitter LED
  • Your benefits

  • Two channels can be configured independently of one another
  • Simple commissioning and product changeover via external teach input
  • No mutual effects from fiber-optic heads mounted in close proximity on account of bus communication
  • Easy monitoring of process parameters
  • Time delays can be adjusted individually to suit the application
  • APC for long-term stable detection
  • Alarm output for reliable detection in adverse conditions
