Sick WLL180T-L432 Overview



Photoelectric fiber optic switch WLL180T-L432 Base unit, NPN, cable 2 m

Sick WLL180T-L432 Description



  • Selectable response time up to 16 s
  • Sensing range up to 20 m, sensing distance up to 1400 mm
  • Bus-compatible with anti-interference
  • 2 x 4-digit display
  • Adjustable hysteresis
  • Rotatable display screen
  • High-resolution signal processing
  • Programmable time delays
  • Your benefits

  • Extremely rapid processes are detected reliably
  • Workpieces are detected reliably even under the most difficult of ambient conditions such as dust, spray or mist
  • No mutual effects from fiber-optic heads mounted in close proximity due to bus communication
  • Easy monitoring of process parameters
  • Hysteresis can be adapted to suit the application, e.g. when detecting tiny or transparent objects
  • The display is easy to read, even under difficult installation conditions
  • Tiny objects can be detected due to the high-resolution signal processing
  • Time delays can be adjusted individually to suit the application
