Laser Class 3R
The sensors fall within laser class 3R. The laser is operated on a pulsed mode, the maximum optical power is ≤ 5 mW. The pulse
frequency depends on the adjusted measuring rate (0.25 ... 10 kHz). The pulse duration of the peaks is regulated depending on the
measuring rate and reflectivity of the target and can be 4 up to 3995 µs.
Laser radiation. Use suitable protective equipment and close your eyes or immediately turn away if the laser
beam hits the eye. Irritation or injury of the eyes possible.
i
Observe the laser protection regulations.
Accordingly, the following applies: The accessible laser radiation is harmful to the eyes. Looking directly into the laser beam is harmful
to the eyes with laser class 3R devices. Reflections of shiny or mirroring surfaces are also harmful to the eyes.
Class 3R laser sensors require a laser protection officer.
Mark the laser area recognizable and everlasting. During operation the laser area has to be restricted and marked.
The following warning labels are attached to the sensor cable:
