Laser Safety
The optoNCDT ILR2250 works with a semi-conductor laser at a wavelength of 655 nm (visible/red).
The sensors fall within laser class 2. The laser is pulsed; the maximum optical power is ≤ 1 mW. The pulse frequency de
-
pends on the measuring rate set (1 ... 20 Hz). The pulse duration of the peaks is controlled depending on the measuring
rate and the reflectivity of the measuring object and can be 0.2 ... 0.8 ns.
Laser radiation. Close your eyes, or immediately turn away if the laser beam hits the eye. Eyes could
become irritated or damaged.
i
Observe the laser regulations!
When operating the sensors, the relevant regulations in accordance with DIN EN 60825-1 (VDE 0837, Part 1, dated
07/2015) and the accident prevention regulation on laser radiation (DGUV 12 [regulation of the Employers’ Liability Insur-
ance] dated 04/2007) valid in Germany must be observed. The following apply accordingly:
-
With class 2 laser devices, the eye is not endangered by random, brief exposure to laser radiation, i.e. exposure times
of up to 0.25 s.
-
Class 2 laser devices may therefore 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.
Class 2 laser devices are not subject to reporting and a laser protection officer is not required.

If both information signs are covered over when the unit is installed, the user must ensure that supplementary infor-
mation signs are attached at the installation location.
Operation of the laser is indicated visually by the LED on the sensor,
