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.
