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
sensing range: Reduce the
distance between the sender
and the receiver, and check
against graphic H. / Check
sensing range and adjust if
necessary; see graphic H. /
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 recei‐
ver. / Clean the optical surfa‐
ces . / Readjust the sensitivity
(potentiometer) / If the poten‐
tiometer is set to the max.
sensing range: Reduce the
distance between the sender
and the receiver, and check

necessary; see graphic H. /
With health output: Check the
power supply, check all electri‐
cal connections (cables and

Swap the sender and receiver
arrangement at every se‐
cond photoelectric through-be‐
am sensor and ensure that
there is sufficient distance
between the through-beam
photoelectric sensors /
