Class 1/2 (I/II) lasers are not notifiable and a laser protection officer is not required either.
The housing of the optical sensors may only be opened by the manufacturer. For repair and service purposes
the sensors must always be sent to the manufacturer.
The laser warning labels for Germany have already been applied. Those for other non German-speaking
countries an IEC standard label and the label for USA are included in delivery and the versions applicable to
the user‘s country must be applied before the equipment is used for the first time.
The following warning label is attached on the sensor housing (bottom side):

iIf both warning labels are disguised in operation mode the user must add additional warning labels.
During operation of the sensor the pertinent regulations according to EN 60825-1 on “radiation safety of laser
equipment“ must be fully observed at all times. The sensor complies with all applicable laws for the manufac-

Although the laser output is low looking directly into the laser beam must be avoided. Due to the visible light
beam eye protection is ensured by the natural blink reflex.
iDo not look directly into the laser beam!
Close your eyes or turn away promptly if laser radiation strikes your eyes.

Functional Principle, Technical Data

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

with another type.
The sensor contains two switching outputs and one external trigger input and trigger output (all of them
parameterizable).
A distance measurement can be triggered:
- via RS232 interface or RS422 interface
- via Profibus DP-V0
- by an external source (in external trigger mode).

Installation and Mounting
optoNCDT ILR 1191
The laser beam must be directed perpendicularly onto the surface of the target. In case of misalignment it is
possible that the measurement results will not always be accurate. Measurements against tilted targets are
possible but depend on the surface characteristics of the target.
For integration of the sensor, two different versions of mechanical attachment are available:
- Attachment to a lateral surface. The sensor provides three support pads, see Fig. 5, reference 1, with
mounting holes M4 x 6.
- Attachment to casing bottom. The sensor provides three support pads, see Fig. 5, reference 2, with
mounting holes M4 x 6.
The sensor will be aligned by a visible laser beam (pilot laser) with the target. To align the sensor, please
comply with the “Instructions for Operation“, see Chap. 9.

The zero-point of the sensor is identical with the outer surface plane of the front cover plate.
5.2 Reflector Mounting
The sensor measures distances to moving and static targets:
- in the range from 0.5 m up to 300 m for natural, diffuse reflecting surfaces with a reflectivity of 90 %,
- between 300 m and 3.000 m to a reflector (for example Scotchlite Engineer Grade type I, series 3290, from
3M)
The pilot laser, see Fig. 2, reference 6, supports the sensor alignment to a given target during commission-
ing. It qualifies as a class 2 (II) laser device and operates at 635 nm (red) in the visible range. The pilot laser

Page 20

is not aligned to emit in a direction parallel with the measurement laser. Instead, its beam intersects with that
of the measurement laser at a distance of 75 m. The tolerance on pilot laser position in relation to the invisible
measurement laser as a function of the distance to a target being measured is shown in the following draw-
ing, see Fig. 7.

When aligning check as follows:
Move the sensor at a very short distance to the reflector (for example < 1 m). The light spot is located in
the lower left corner of the reflector.
Move the sensor with the longest range to the reflector. Check the position of the light spot at the reflec-
tor and set it if necessary.
