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.

Measures /
Measures
(we recommend only using
SICK reflectors) / Check sen‐
sing range and adjust if ne‐
cessary; see graphic H. / Dis‐
tance between the sensor and
the reflector is too long / With
health output: Check the
power supply, check all electri‐
cal connections (cables and
plug connections). /
Check the operating conditi‐
ons: Fully align the beam of
light (light spot) with the re‐
flector. / Clean the optical sur‐
faces (sensor and reflector). /
Readjust the sensitivity (po‐
tentiometer) / If the potentio‐
meter is set to the max. sen‐
sing range: Reduce the dis‐
tance between the sensor and
the reflector, and check the re‐
flector type against graphic
H. / Reflector is not suitable
for the application in question
(we recommend only using
SICK reflectors) / Check sen‐
sing range and adjust if ne‐
cessary; see graphic H. / Dis‐
tance between the sensor and
the reflector is too long / With
health output: Check the
power supply, check all electri‐
cal connections (cables and
plug connections).
