Functional Principle, Technical Data
The optoNCDT ILR 1181/1182 is a laser range finder to measure distances from 0.1 m up to 150 m with
pinpoint accuracy. A given target can be clearly identified with the help of a red laser sighting point. In terms
of operating reach, the optoNCDT ILR 1181/1182 performs depending on the reflectance, morphology and
qualities of the target to be measured.
The range finder works based on comparative phase measurement. It emits modulated high-frequency light
which is diffusely reflected back from the target with a certain shift in phase to be compared with a reference
signal. From the amount of phase shift, a required distance can then be determined with millimeter accuracy.
A distance measuring cycle can be triggered in four different ways:
- By sending a command from the PC or another equivalent control unit
- By making appropriate prior parameter settings for the autostart command and applying supply voltage
- By external triggering (in remote-trigger mode)
- Using the autostart trigger function.
For a more detailed description of these four trigger options, see Chap.

Special performance features are:
- Provides high accuracy and great reach under extreme outdoor temperatures.
- Works in a wide range of operating voltages from 10 VDC to 30 VDC from an onboard vehicle supply
point, an industrial direct voltage supply net or a DC power pack.
- Features consistently low power consumption of < 1.5 W (without I
Alarm
).
- Up to 30 m reach for distance measurement, up to 150 m if additional reflectors are mounted onto the
target (depending on reflectance and environmental conditions).
- Visible laser beam for easier sighting.
- RS232/422 interface port for input of measuring functions and commands from, and output of measured
values to, a PC or a laptop.
- Switching output and analog output are separately programmed.
- Switching output with adjustable limit to indicate positive and negative excession of preselectable distance
range window by sighting distance.
- Measured values can be displayed in meters, decimeters, centimeters, feet, inches due to.
- Option for remote triggering of a measurement from an external trigger device.
