3. Functional Principle, Technical Data
The optoNCDT ILR 1191 is a laser-based distance sensor for non-contact and precise distance and displace-
ment measurements from 0.5 m up to 3.000 m. The sensor is designed for very large measuring ranges, with
and without reflector. Due to the very high measuring rate of the sensor, moving objects can be measured
easily. The sensor operates according to the laser pulse runtime principle and is therefore particularly well
suited to applications with large distances. Commissioning of the sensor is straightforward due to a variety of
interfaces and easy mounting options. The optoNCDT ILR 1191 is fitted with an integrated heater for outdoor
use. A pilot laser is also integrated for mounting and adjustment.
The sensor measures distances to moving and static targets:
- with measuring range from 0.5 m up to 300 m on diffuse reflective surfaces with 90 % reflectivity,
- with measuring range from 300 m up to 3.000 m on reflector surfaces, for example Scotchlite series 3290,
The sensor is used for speed measurement from 0 m/s up to 100 m/s (at 0.5 m up to 700 m distance).

Fig. 2 Elements of a sensor
With the help of a visible red laser sighting point (pilot laser) a given target can be unequivocally identified.
The actual range of measurement depends on the reflectivity and the surface quality of a target being mea-
sured. The sensor is available with RS232 or RS422, depending on the customer’s request. Product manufac-
turing includes the installation of a requested configuration. Once installed, the interface cannot be replaced
