The sensor must be disposed of according to the applicable country-specific regula‐
tions. Efforts should be made during the disposal process to recycle the constituent
materials (particularly precious metals).
SICK sensors are maintenance-free.
We recommend doing the following regularly:
• Clean the external lens surfaces
•
Check the screw connections and plug-in connections
No modifications may be made to devices.

DISASSEMBLY AND DISPOSAL
Cause
Remission capability of the
background is excessive
Sensitivity is set too low or dis‐
tance between the sensor and
the object is too long
Remission capability of the
object is insufficient
Measures
Check changes to the back‐
ground. Reduce the sensitivity
of the sensor or use sensors
with background suppression
Increase the sensing range,
take note of the distance
between the sensor and the
background
Increase the sensing range,
take note of the distance
between the sensor and the
background
