Advantages of Protective Film
Streaks or scratches on the glass window of the sensor lead to unwanted reflections in the beam
path and thus to less accurate measurement results.
A protective film
- prevents scratches on the glass window,
- can be changed if necessary.
Preparation
Disconnect the sensor from the power supply or switch the power supply off. Alternatively,
switch off the laser light source in the sensor. To do this, use the control input Laser on/
off; see operating or assembly instructions.
Before applying the protective film, check that the laser is switched off.
Clean the glass surface with a lint-free cloth.
Gently wipe the glass surface with the lint-free cloth.
Procedure
Remove the protective film from the carrier film.
Hold the carrier film by the edges, bend at the kink and remove the protective film from the
carrier film.
Stick the protective film on the sensor
i
The regions where the laser beam exits and the optical receiving system for the reflected
laser light must be completely covered by the protective film.
Place the protective film on the glass window and smooth over it. To do this, use a lint-free
cloth. Make sure no bubbles form.
Important
- Completely cover laser beam exit and optical
receiving system
- No air pockets between glass window and
protective film
If there are air pockets between the protective film and the glass window after the film has been
applied, do not attempt to remove them. Remove the protective film and start again with a new
protective film as per the section Preparation.

Warnings
The sensor emits laser radiation during operation. Eyes could become ir-
ritated or damaged. Close your eyes, or immediately turn away if the laser
beam hits the eye.
Disconnect the sensor from the power supply or switch the power supply off.
Alternatively, switch off the laser light source in the sensor. To do this, use the control input
Laser on/off; see operating or assembly instructions.
