  • Page 12: Functional Principle, Technical Data

    Functional Principle, Technical Data Short Description The optoNCDT 1220 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.

  • Page 17: Installation

    5.1.2.1 Light from other Sources Thanks to their integrated optical interference filters the optoNCDT 1220 sensors offer outstanding perfor- mance in suppressing light from other sources. However, this does not preclude the possibility of interference from other light sources if the objects being measured are shiny and if lower measuring rates are selected.

  • Page 18: Color Differences

    If the objects being measured are fast moving and the measuring rate is low, it is possible that movement blurs may result. Always select a high measuring rate for high-speed operations, therefore, in order to prevent errors. optoNCDT 1220 Page 18...

  • Page 22: Mounting, Dimensions

    Installation Mounting, Dimensions The optoNCDT 1220 sensor is an optical system for measurements with micrometer accuracy. The laser beam must be directed perpendicularly onto the surface of the target. In case of misalignment it is possible that the measurement results will not always be accurate.

  • Page 37: Timing, Measurement Value Flux

    Operation Timing, Measurement Value Flux The sensor requires three cycles for measurement and calculation without triggering: Each cycle takes 1000 μs at a measuring rate of 1 kHz. The measured value N is available at the output after  three cycles. The delay between acquisition and output is therefore 3000 μs. As the processing in the cycles  occurs parallel, after another 1000 μs, the next measured value (N+1) is output. optoNCDT 1220 Page 37...

The zeroing function can also be combined with the select key. 1) The zeroing is not applied when LED State is red, flash frequency 8 Hz for 2 s. optoNCDT 1220 Page 41...

  • Page 42: Signal Processing

    If no valid measurement value can be detected, an error is output. If this disrupts further processing, you can alternatively hold the last valid value over a specific period of time i.e. it can be output again. After expiry of the chosen number an error value is output. optoNCDT 1220 Page 42...

  • Page 43: Triggering

    Triggering 7.4.4.1 General The optoNCDT 1220 measurement output is controllable through an external trigger signal or a command. Triggering affects the analog and digital output. The measurement value at the time of triggering is output delayed, see Chap. 6.3. - Triggering does not influence the measuring rate resp. the timing so that between the trigger event (level change) and the start of output always lie 3 cycles + 1 cycle (Jitter).

  • Page 44: Value Output Trigger

    Measurement values are calculated continuously and independently of the trigger event. A trigger event simply triggers the value output via a digital interface. Therefore, any values measured immediately before the trigger event are included in calculating mean values (averages). optoNCDT 1220 Page 44...
