2. Laser Safety
2.1 scanCONTROL 2900-100
The scanCONTROL 2900-100 sensors operate with a semiconductor laser with a wave-
length of 658 nm (visible/red). Operation of the laser is indicated visually by the LED on
the sensor.
When operating the scanCONTROL 2900-50 sensors, the relevant regulations in accord-
ance with DIN EN 60825-1 (IEC 60825, Part 1, dated 07/2015) and the applicable acci-
dent prevention regulation must be observed.
The housings of the optical scanCONTROL 2900-50 sensors may only be opened by
authorized personnel
, see 1.6 . For repair and service purposes, the sensors must always
be sent to the manufacturer.
2.2 Laser class 2M
The scanCONTROL 2900-100 sensors with a max. laser output up to 8 mW , see 9.4
(Section 3.2) have been assigned to laser class 2M (IIM).
The following applies accordingly:
With class 2M laser devices, the eye is not endangered by random, brief exposure to
laser radiation, i.e. exposure times of up to 0.25 s.
Directly looking into the beam can be dangerous, if the eye-closure reflex is consciously
suppressed, e.g., during adjusting. Directly looking into the beam with optical devices,
such as magnifying glasses, is dangerous.
Class 2M laser devices may be used without further protective measures if you do not
intentionally look into the laser beam or into specular-reflected radiation for more than
0.25 s.
Because the presence of the eyelid protective reflex should not normally be assumed,
one should deliberately close the eyes or turn away immediately if the laser beam hits
the eye.
The following signs are attached to the front and back of the sensor housing:

Fig. 5 Laser warning symbol 2900-50, class 2M
Laser warning signs for Germany have already been printed on the device. The warning
signs for the EU and US are included and must be attached for the appropriate region by
the user prior to initial operation of the device.
Class 2M laser devices are not subject to reporting and a laser protection officer is not
required. Mark the laser area clearly and permanently.
i
If both warning signs are covered over when the unit is installed, the user must
ensure that supplementary warning signs are attached at the installation location.

CAUTION
Danger to the eyes due
to laser light!
Consciously close your
eyes or immediately turn
away if the optical radia-
tion enters the eye.
