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).
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
receiver. / Clean the optical
surfaces / If the potentiome‐
ter is set to the max. sensitiv‐
ity: Reduce the distance
between the sender and the
receiver / Check sensing
range and adjust if necessary,
see Figures 6-7 and
table

Swap the sender and receiver
arrangement at every sec‐
ond through-beam photoelec‐
tric sensor and ensure that
there is sufficient distance
between the through-beam
photoelectric sensors, see
