CAUTION
Optical radiation: Class 2 Laser Product
The human eye is not at risk when briefly exposed to the radiation for up to 0.25
seconds. Exposure to the laser beam for longer periods of time may cause damage to
the retina. The laser radiation is harmless to human skin.
■Do not look into the laser beam intentionally.
■Never point the laser beam at people's eyes.
■If it is not possible to avoid looking directly into the laser beam, e.g., during
commissioning and maintenance work, suitable eye protection must be worn.
■Avoid laser beam reflections caused by reflective surfaces. Be particularly careful
during mounting and alignment work.
■Do not open the housing. Opening the housing may increase the level of risk.
■Current national regulations regarding laser protection must be observed.
WARNING
Electrical voltage!
Electrical voltage can cause severe injury or death.
■Work on electrical systems must only be performed by qualified electricians.
■The power supply must be disconnected when attaching and detaching electrical
connections.
■The product must only be connected to a voltage supply as set out in the require‐
ments in the operating instructions.
■National and regional regulations must be complied with.
■Safety requirements relating to work on electrical systems must be complied with.
WARNING
Risk of injury and damage caused by potential equalization currents!
Improper grounding can lead to dangerous equipotential bonding currents, which may
in turn lead to dangerous voltages on metallic surfaces, such as the housing. Electrical
voltage can cause severe injury or death.
■Work on electrical systems must only be performed by qualified electricians.
■Follow the notes in the operating instructions.
■Install the grounding for the product and the system in accordance with national
and regional regulations.
2.8 Warning signs on the device
A class 2 laser is installed in the device. The housing is labeled with a warning sign.

3.2 Function
The device consists of a laser, receiving optics and an integrated evaluation unit. The
laser emits a light beam which is reflected back to the receiving optics by the reflector.
The integrated evaluation unit determines the distance between the sensor and the
reflector using phase-correlated time-of-flight measurement.
For the measurement, either the reflector or the device can move in a linear fashion
along the laser beam.
The measured distance is transmitted via the data interface and can be used for
control purposes or in a position control loop, for example.

RUN
The device is in “measured value display” operating mode
when it is switched on. The RUN symbol and the current dis‐
tance value are displayed. This operating mode enables you
to display other process values.
EscSet
Menu
MEN
The MEN symbol is displayed in “menu display” operating
mode. In this operating mode, device parameters can be read
out or set depending on the interface.
NOTE
In the display, distance values always have the resolution “mm”, speed values the reso‐
lution “mm/s”. Positive numerical values do not have a sign, negative numerical values
have the “-” sign. This limits the display range to 5 decimal places when numerical
values are negative. In the “measured value display” operating mode, the sign and
the highest decimal place are cut off and replaced by a "!" when the value -99,999 is
undercut.
3.4.3 Operating pushbuttons
The device can be operated using the following 4 pushbuttons:

5 Mounting
5.1 Mounting procedure
1. Choose a mounting site bearing in mind the mounting instructions, see "Mounting
instructions", page 18.
2. Selecting and mounting the reflector, see "Select and mount the reflector ",
page 18.
3. Mounting alignment bracket and distance sensor, see "Mounting the alignment
bracket and distance sensor", page 25.
4. Establishing electrical connection, see "Electrical installation", page 30.
5. Aligning distance sensor and reflector to one another see "Aligning the distance
sensor and reflector with each other", page 27.
5.2 Mounting instructions
•Observe the technical data.
•Protect the sensor from direct sunlight.
•To prevent condensation, avoid exposing the device to rapid changes in tempera‐
ture.
•The mounting site has to be designed for the weight of the device.
•Use a sensor with optional heater at low ambient temperatures such as in cold
storage.
•Use a sensor with an optional cooler housing at higher temperatures.
•Maintain a sufficient distance to other distance sensors, see "Placement of multi‐
ple distance sensors", page 21.
•Maintain a sufficient distance to the data transmission photoelectric sensors, see
"Arranging the distance sensor to the adjacent optical data transmission system",
page 23.
5.3 Select and mount the reflector
NOTE
You can find suitable reflectors and suitable reflective tape at www.sick.com/DX100.
Reflector size
■Select a reflector size that always allows the entire light spot to hit the reflector.
■If the reflector is mounted to a vehicle and the distance sensor is secured in place
at a fixed location, you can calculate the minimum size of the reflector using the
distance-based light spot size, see "Optics", page 85.
■If the distance sensor is installed onto a vehicle, a larger reflector is typically nec‐
essary for taking into account the rolling movements of the vehicle and therefore
of the laser.
NOTE
The reflector must always be at least 100 mm x 100 mm in size, even if the light
spot is smaller due to a shorter measuring distance.
Reflector tilt
bTo avoid direct surface reflections, mount the reflector with a tilt of approx.
+1° … +3° in one of the 2 axes (horizontal or vertical).

■Shiny surfaces that are parallel to the laser beam axis may cause beam switching
or light scatter and lead to incorrect measurements as a result. Therefore, align
the reflector by giving it a 1 ... 3° tilt away from shiny surfaces into the free space.
Shiny surfaces include, for example, storage profiles, pallets with stretch film,
poles or rails.
■If the sensor is mounted in the driving axis of an automated storage and retrieval
system, tilt the reflector toward the ceiling away from the rail .see figure 6,
page 20.
■If the sensor is mounted in the stroke axis of an automated storage and retrieval
system, tilt the reflector away from the mast system see figure 7, page 21.
