Picture of Linear displacement sensor optoNCDT 1750

Linear displacement sensor optoNCDT 1750

  • Laser sensor with special lens and oval light spot (small laser line)
  • Ideal for static and dynamic distance measurements on metals, structured surfaces, and measuring objects where the laser beam penetrates
  • Integrated controller
  • Measuring ranges (mm): 2 | 10 | 20 | 50
  • Linearity from 1.6 µm
  • Resolution max. 0.1 µm
  • Adjustable measuring rate up to 7.5 kHz
  • Interfaces: analog output, RS422, PROFINET, EtherNet/IP
  • Real-time adaption to changing surfaces (RTSC)
  • Manufacturer:


    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-resolving element (CMOS) by a receiver optic which is arranged to the optical axis of the laser beam at 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.

    The optoNCDT 1750 system is designed for use in industrial and laboratory applications.

    It is used ƒ

    • for measuring displacement, distance, and position ƒ
    • for in-process quality control and dimensional testing

    The system must only be operated within the limits specified in the technical data. 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.
