harmonized standards (EN) listed therein. The EU Declaration of Conformity is available to the responsible
authorities according to EU Directive, article 10, at:
MICRO-EPSILON MESSTECHNIK
GmbH & Co. KG
Königbacher Straße 15
94496 Ortenburg / Germany
The sensor is designed for use in industrial environments and meets the requirements.

1.4 Intended Use
- The optoNCDT 1750 system is designed for use in industrial and laboratory applications.
- It is used
for measuring displacement, distance and position
for in-process quality control and dimensional testing
- The system must only be operated within the limits specified in the technical data, see Chap. 3.3.
- The sensor must be used in such a way that no persons are endangered or machines and other material
goods are damaged in the event of malfunction or total failure of the sensor.
- Take additional precautions for safety and damage prevention in case of safety-related applications.
1.5 Proper Environment
- Protection class: IP 65 (applies only when the sensor cable is plugged in)
Lenses are excluded from protection class. Contamination of the lenses leads to impairment or failure of the
function.
- Operating temperature: 0 °C ... 50 °C (+32 up to +104 °F)
- Storage temperature: -20 °C ... 70 °C (-4 up to +158 °F)
- Humidity: 5 - 95 % (non-condensing)
- Ambient pressure: Atmospheric pressure
iThe protection class is limited to water, no penetrating liquids or similar!

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.
iComply 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:

Do not stare into the beam

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. 5.3.

3. Functional Principle, Technical Data
3.1 Short Description
The optoNCDT 1750 uses the principle of optical triangulation, that is, a visible, modulated point of light is
projected onto the target surface.
The diffuse part of the reflection of this point of light is displayed depending on distance on a position-resolv-
ing element (CMOS) by an receiver optic which is arranged to the optical axis of the laser beam in a defined
angle.
A signal processor in the sensor calculates the distance of the point of light on the measuring object to the
sensor by means of the output signal of the CMOS elements. The distance value is linearized and output by
means of the analog or RS422 interface.

3.2 Real Time Control (RTSC)
The CMOS element determines the intensity of incident light during the exposure. This enables the sensor to
compensate for fluctuations in brightness on the object being measured. What is more, it does so in a range
from almost total absorption to almost total reflection. The RTSC (Real-Time-Surface-Compensation) allows
an accurate real-time surface compensation in the measurement process with a high dynamic range.
