At a glance
  • Four measuring ranges from 50 mm up to 1,000 mm
  • Very high linearity of up to ± 0.5 mm
  • CMOS receiving element enables accurate distance measurement independent of color or shininess
  • Red laser
  • Scaleable analog and switching output
  • Display with easy to use setup menu
  • Advanced settings (e.g., averaging function, external laser-off, etc.)
Your Benefits
  • Reliable, precise measurement, independent of surface, increases production quality
  • Reliable and consistent measurements, regardless of color, reduce changeover time
  • Advanced settings provide increased application flexibility to easily solve customer-specific applications
  • Fast commissioning via button, remote or numerical teach
  • Easy, precise alignment and verification based on red laser light and LC display, decreasing commissioning time
  • Tough metal housing permits operation in harsh environments

Ambient temperature

Operation –20 °C ... +55 °C 6)

Storage –40 °C ... +60 °C

Data interface 1 x 4 mA ... 20 mA (< 300 Ω)

1) 6 % ... 90 % remission.
2) The models with measuring range of 100 mm ... 1,000 mm meets the specification of the models with measuring range of 100 mm ... 1,000 mm for distances
< 600 mm.
3) Dependent on the averaging setting: fast/medium/slow.
4) When calibrated in the application regularly.
5) PNP: HIGH = VS - (< 2 V) / LOW = < 2 V, NPN: HIGH = < 2 V / LOW = VS.
6) Operating temperature at VS = 24 V.
