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).
NOTE
Disposal of batteries, electric and electronic devices
• According to international directives, batteries, accumulators and electrical or
electronic devices must not be disposed of in general waste.
• The owner is obliged by law to return this devices at the end of their life to the
respective public collection points.
•
This symbol on the product, its package or in this document, indicates
that a product is subject to these regulations.
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.
Subject to change without notice. Specified product properties and technical data are
not written guarantees.
Cause
a) Insufficient alignment
b) Contamination of the
optical surfaces
c) Particles in the light
beam
d) Distance between sen‐
sor and reflector is too
large
e) Reflector is not suitable
Distance between sensor and
reflector is too large / light
beam is not completely
aligned to the reflector /
reflector is not suitable / Front
screen and/or reflector is con‐
taminated.

Measures
3. Check electrical connections
a) Check alignment
b) Cleaning of the optical
surfaces (sensor and
reflector).
c) Avoid contamination in
the air as far as possible
d) Check sensing range
e) SICK reflector is recom‐
mended
Check sensing range / check
alignment / SICK reflector is
recommended / Cleaning of
the optical surfaces (sensor
and reflector).
