Avoid exposure of sensor to aggressive media (detergents, cooling emulsions). > Damage to or destruction of the sensor Notes on CE Marking The following apply to the optoNCDT 1220: - EU Directive 2014/30/EU - EU Directive 2011/65/EU Products which carry the CE mark satisfy the requirements of the EU directives cited and the relevant appli- cable harmonized European standards (EN).
Safety Intended Use - The optoNCDT 1220 system is designed for use in industrial and laboratory applications. - It is used for measuring displacement, distance, position and thickness for in-process quality control and dimensional testing - The sensor must only be operated within the limits specified in the technical data, see Chap. 3.3.

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.
Functional Principle, Technical Data Auto Target Compensation (ATC) The Auto Target Compensation (ATC) enables stable compensation independent of color and brightness of the measuring object. Also small objects can be detected reliably thanks to the small measuring spot. optoNCDT 1220 Page 15...

CMOS signal in real time and subsequent compensation, see Chap. 3.2. Dark or shiny objects being measured, e.g. black rubber, may require longer exposure times. The exposure time is dependent on the measuring rate and can only be increased by reducing the sensor’s measuring rate. optoNCDT 1220 Page 19...
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.
Ceramic reference surface Structured surface Recommendation for parameter choice: - The averaging number should be selected in such a way that a surface area the size of which is compa- rable to those with mechanical measurements is averaged. optoNCDT 1220 Page 21...
These influences have to be explicitly considered when scanning profiled surfaces. Basically the angle be- havior of triangulation is liable to the reflectivity of the measuring object surface.

In case of bore holes, blind holes and edges in the surface of moving targets the sensor must be arranged in such a way that the edges do not obscure the laser spot. incorrect correct (shadow) Fig. 8 Sensor arrangement for holes and ridges optoNCDT 1220 Page 23...
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.

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 39...

After zero setting, the sensor will provide new readings relative to the measurement value during zero setting. Zeroing requires that a target is within the measurement range. Zeroing has an influence on the analog and digital output. optoNCDT 1220 Page 41...

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 44...
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 timing so that between the trigger event (level change) and the start of output always lie 3 cycles + 1 cycle (Jitter).
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 46...

The sensor continues to deliver measurement values to the RS422 output even while communicating with the sensor. For the data transmission with a PC the MICRO-EPSILON IF2001/USB is suitable. The IF2001/USB combines the three bytes for the data word and saves them in the FIFO. The 18 bits are used for measurement values and error values.
The liability for material defects is 12 months from delivery. Within this period, defective parts, except for wearing parts, will be repaired or replaced free of charge, if the device is returned to MICRO-EPSILON with shipping costs prepaid. Any damage that is caused by improper handling, the use of force or by repairs or modifications by third parties is not covered by the liability for material defects.
