Intended Use
The optoNCDT 1900 is designed for use in industrial and laboratory applications. It is used for
measuring displacement, distance and position as well as in quality control and dimensional
testing.
The sensor must only be operated within the limits specified in the technical data, see operating
instructions, 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-relat-
ed applications.
Warnings
Connect the power supply according to the safety regulations for electrical equipment. The sup-
ply voltage must not exceed the specified limits.
> Risk of injury, damage to or destruction of the sensor.
Avoid constant exposure of the sensor to splashes of water. Avoid exposure of sensor to aggres-
sive media (detergents, cooling emulsions).
> Damage to or destruction of the sensor
Avoid shock and vibration to the sensor. Protect the sensor cable against damage.
> Damage to or destruction of the sensor, failure of the measuring device.
Proper Environment
- Protection class: IP67 (applies only when sensor cable is plugged in)
Lenses are excluded from the protection class. Contamination of the lenses causes impairment
or failure of the function.
- Temperature range
- Humidity:
5 ... 95% (non-condensing)
Operation: 0 ... +50 °C
- Ambient pressure: Atmospheric pressure
Storage:
-20 ... +70 °C
Sensor Mounting
The optoNCDT 1900 sensor is an optical system for measurements with micrometer accuracy.
Ensure careful handling during installation and operation!
Mount the sensor only to the existing through-bores (mounting holes) on a flat surface. Any
type of clamping is not permitted.
Mount the sensor using two M4 screws or the via the through-bores for M3 using the
screws from the accessories.

Industrial Ethernet with PoE
Sensor supply is via a PoE-capable switch. Phantom powering (PoE) is possible via the
- PC1900-IE-x/RJ45
- PC1900-IE-x/OE-RJ45
cables.

As an alternative to PoE, the sensor can be supplied with the optional PS2020 power supply unit.
Voltage supply only for measuring devices, not to be used for drives or similar sources of impulse
interference at the same time. MICRO-EPSILON recommends using an optional available power
supply unit PS2020 for the sensor.
Only turn on the power supply after wiring has been completed.
Connect the inputs Pin 1 and Pin 2 at the sensor with a 24V power supply.

Laser Safety
The optoNCDT 1900 operates with a semiconductor laser with a wavelength of 670 nm (visible/
red) or 658 nm (visible/red). Operation of the laser is indicated visually by the LED
state
on the
sensor. When operating the optoNCDT 1900 sensors, the relevant regulations according to IEC
60825, Part 1 of 05/2014 and the applicable accident prevention regulations must be followed.
i
If both warning labels are covered over when the unit is installed, the user must ensure that
supplementary labels are applied.
Laser Class 2
The sensors fall within laser class 2. The laser is operated on a pulsed mode, the maximum optical
power is ≤ 1 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.

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.
