SICK WL34-R240 Description



  • High operating reserve at a long range
  • Switch selectable PNP or NPN output
  • and light/dark switching
  • Versions with DC voltage (10...30V) or universal AC/DC voltage (12 240 V DC / 24 240 V AC)
  • Optional test input, adjustable ON and OFF time delays, alarm output
  • M12 or terminal chamber connection: 90 rotatable
  • UL approval
  • Your benefits

  • High operating reserve at a long range minimizes downtime
  • Alarm output provides early warning that maintenance may be needed
  • Test input allows users to validate that the sensor is operating as expected
  • The sensor cover protects configuration components against environmental hazards
  • Adjustable time delay, alarm output, test input, and universal AC/DC voltage provide additional flexibility and reduce the number of part numbers needed
