The sensor must be disposed of according to the applicable country-specific regulati‐
ons. Efforts should be made during the disposal process to recycle the constituent ma‐
terials (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.
Subject to change without notice. Specified product properties and technical data are
not written guarantees.

Check the operating conditi‐
ons: Fully align the beam of
light (light spot) with the back‐
ground. / Clean the optical
surfaces . / Readjust the sen‐
sitivity (potentiometer) /
Check sensing range and ad‐
just if necessary; see graphic
