Laser Safety
optoNCDT 1750
Never deliberately look
into the laser beam!
Consciously close
your eyes or turn away
immediately if ever the
laser beam should hit
your eyes.
2. Laser Safety
The optoNCDT 1750 sensors operate with a semiconductor laser with a wavelength of 670 nm (visible/red).
The sensors fall within Laser Class 2 (II). The laser is operated on a pulsed mode, the average power is
≤ 1 mW. The pulse frequency depends on the adjusted measuring rate (0.3 ... 7.5 kHz). The pulse duration
of the peaks is regulated depending on the measuring rate and reflectivity of the target and can be 0 up to
3333 µs.

Comply with all regulations on lasers!
Although the laser output is low looking directly into the laser beam must be avoided. Due to the visible light
beam eye protection is ensured by the natural blink reflex. The housing of the optical sensors may only be
opened by the manufacturer, see Chap.
12. For repair and service purposes the sensors must always be sent
to the manufacturer.
Lasers of Class 2 (II) are not subject to notification and a laser protection officer is not required.
The following warning labels are attached to the cover (front and/or rear side) of the sensor housing:

During operation of the sensor the pertinent regulations acc. to IEC 60825-1 on „radiation safety of laser
equipment“ must be fully observed at all times. The sensor complies with all applicable laws for the manufac-
turer of laser devices.
Laser operation is indicated by LED, see Chap.
