SENSORS & SENSING SYSTEMS
NEW LASER TRIANGULATION SENSOR FEATURES INTEGRATED INDUSTRIAL ETHERNET INTERFACE
New from Micro-Epsilon is the compact optoNCDT 1900-EtherCAT, which provides direct connection to industrial controllers, eliminating the need for an external interface module and reducing installation effort and wiring. With the optoNCDT 1900-EtherCAT, signal
conversion takes place directly in the sensor, without loss of speed and with full performance. After rebooting in EtherCAT mode, all the sensor settings are automatically applied to the TwinCAT software, which means time consuming settings made directly in TwinCAT are no longer necessary. Less experienced TwinCAT users are able therefore to quickly integrate the sensor into the EtherCAT control unit. For very fast measurements, that would
normally be limited by the PLC’s cycle time, an oversampling function can be activated in the sensor, allowing measurement data to be transferred four times faster than the cycle time of the PLC (up to a maximum of 10kHz). For a PLC with a 1ms cycle time, this means a possible sensor measuring rate of 4kHz. For this purpose, the data is temporarily stored by the sensor and only transmitted with the next query cycle. This laser triangulation sensor is available
in seven measuring ranges from 2-500mm and offers linearity from ±1.0µm. Depending on the application, power can be supplied externally or
via PoE (Power-over- Ethernet). Other industrial fieldbus interfaces, including Profinet and EtherNet/IP, will be available for the optoNCDT 1900 in 2022. A laser line version of
the optoNCDT 1900- EtherCAT is also available. The optoNCDT 1900LL- EtherCAT projects a small laser line onto the measuring object. The sensor performs particularly well in distance measurements where the sensor or measuring object is moved in the Z-axis direction, such as robot positioning. The sensor is designed for shiny metallic and structured surfaces, as well as for measurements of materials where the laser beam penetrates. For these surfaces, the small laser line offers significant advantages, as it optically averages and compensates for irregularities such as structure and roughness. In addition to optical averaging, special software algorithms filter out interferences caused by surface roughness, defects, depressions or the smallest of holes. Especially on metals, they

achieve more stable and reliable measurement results than point sensors. The optoNCDT 1900 series of laser triangulation
sensors is suitable for high speed distance, displacement and position measurements in a wide range of automation tasks, including machine building, robotics, automotive production, 3D printing and coordinate measuring machines.
