Sensor Mounting, Dimensions
The optoNCDT 1750 sensor is an optical system for measurements with micrometer accuracy.
Pay attention to careful handling during mounting and operation.
Mount the sensor only to the existing holes on a flat surface. Clamps of any kind are not
permitted.
Use three M4 screws to mount the sensors. The bearing surfaces surrounding the fastening
holes (through-holes) are slightly raised.

Assembly Instructions
optoNCDT 1750-2DR
Proper Use
The optoNCDT 1750-2DR system is designed for use in industrial and laboratory areas. It is used for
measuring displacement, distance and position as well as in in-process quality control and dimensional testing.
The sensor may only be operated within the limits specified in the technical data, see instruction
manual, Chap. 3.3. The sensor must be used in such a way that no persons are endangered or
machines are damaged in case of malfunctions or total failure of the sensor. Take additional precautions for safety and damage prevention for safety-related applications.
Warnings
Avoid unnecessary laser radiation to be exposed to the human body. Switch off the sensor for cleaning and maintenance, for system maintenance and repair if the sensor is integrated into a system.
Caution - use of controls or adjustments or performance of procedures other than those specified
may cause harm.
Connect the power supply and the display-/output device in accordance with the safety regulations
for electrical equipment. The power supply may not exceed the specified limits.
> Risk of injury. Damage to or destruction of the sensor.
Avoid continuous exposure to splashing water on the sensor and the controller. Avoid exposure to
aggressive materials (washing agent, cooling emulsions) on the sensor.
> 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.
Laser Class
The optoNCDT 1750-2DR sensors operate with a semiconductor laser with a wavelength of 670 nm
(visible/red).
The following warning labels must be attached to the cover (front and rear side) of the sensor
housing:

Multi-Function Input
The multi-function input enables triggering, zero setting/mastering and teaching. The function
depends on the programming of the input and on the timing of the input signal.
The inputs are not electrically isolated. The maximum switching frequency is 10 kHz.

Access via Web Interface
Interactive web pages for programming the sensor now appear in the web browser. The sensor is
active and supplies measurement values. The ongoing measurement can be operated by means
of function buttons in the area Measurement chart.
In the top navigation bar other
auxiliary functions (settings,
measurement
chart etc.) are
available.
The appearance of the websites can change dependent of the functions. Each page contains
descriptions of parameters and so tips for filling the website.
Select a Measuring Rate
Go to the menu Settings > Data recording > Measuring rate.
Start with a medium measuring rate. Select a measuring rate from the list. Confirm with Apply.
Select an Interface
Go to the menu Settings > Output > Output interface.
Defines which interface is used for output of measured values. A parallel output o measured values via multiple channels is not possible. RS422 and analog output cannot be operated simultaneously. While using the web interface, the output is switched off via RS422.
