Functional Principle, Technical Data Functional Principle, Technical Data Short Description The optoNCDT 1420 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 22: Installation
Installation Installation Instructions for Installation 5.1.1 Reflection Factor of the Target Surface In principle the sensor evaluates the diffuse part of the reflected laser light. Laser beam Laser beam Laser beam 2  Ideal diffuse reflection Direct mirror reflection Real reflection Fig.
Page 23: Color Differences
Installation 5.1.2.2 Color Differences Because of intensity compensation, color difference of targets affect the measuring result only slightly. How- ever, such color differences are often combined with different penetration depths of the laser light into the material. Different penetration depths then result in apparent changes of the measuring spot size. Therefore color differences in combination with changes of penetration depth may lead to measuring errors.
Page 24: Surface Roughness
Installation 5.1.2.6 Surface Roughness Laser-optical sensors detect the surface using an extremely small laser spot. They also track slight surface unevenness. In contrast, a tactile, mechanical measurement, e.g. using a caliper, detects a much larger area of the measurement object. In case of traversing measurements, surface roughnesses of 5 µm and more lead to an apparent distance change.
Page 25: Angle Influences
Installation 5.1.2.7 Angle Influences Tilt angles of the target in diffuse reflection both around the X and the Y axis of less than 5 ° only have a disturbing effect with surfaces which are highly reflecting. 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.

Page 27: Mounting, Dimensions
Installation Mounting, Dimensions The optoNCDT 1420 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. Make sure it is handled carefully when installing and operating.

Page 52: Triggering
- 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). - Micro-Epsilon recommends the abdication of data reduction, for example, by sub-sampling when the triggering is used.
Page 53 Set Sensor Parameter Implemented trigger conditions: Level triggering with high level / low level. Continuous measurement input resp. output, as long as the selected level is applied. Then stops the data output. The pulse duration must be at least one cycle time. The sub- sequent break must also be at least one cycle time.
Page 54: Signal Processing - Trigger For Acquiring Values
Set Sensor Parameter 7.4.4.2 Signal Processing - Trigger for Acquiring Values The current field signal is processed only after a valid trigger event, and it is used to calculate the measure- ment values. The measurement values are then forwarded for further calculation (e.g. averaging) and for output via an analog or a digital interface.

Digital Interfaces RS422 Digital Interfaces RS422 Preliminary Remarks The interface RS422 has a maximum baud rate of 1 MBaud. The factory-set baud rate is 921.6 kBaud. The maximum measuring rate is 4 kHz. Data format: Measurement values in binary format, commands as an ASCII string. Interface parameter: 8 Data bits, no parity, one stop bit (8N1).

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 IF2008 PCI BUS interface card is suitable. This can be connected to the sensor via the PCF1420-x/IF2008 interface cable, which is also available as an option.

Page 92: A 3 Ascii Communication With Sensor
Appendix| ASCII Communication with Sensor ASCII Communication with Sensor A 3.1 General The ASCII commands can be sent to the sensor via the RS422 interface. All commands, inputs and error messages are effected in English. One command always consists of a command name and zero or several parameters, which are separated by blanks and are completed with LF.
Page 93 Appendix| ASCII Communication with Sensor „<a>“ The value of the parameter lies in a value range of “... to …“, see parameter description. Parameter values without peak brackets can only assume discrete values, see parameter description. Parantheses are to be understood as a grouping, that is, for a better articulation „P1 P2 | P3“ is written as „(P1 P2)|P3“.
