World leading laser sensor offers 50 kHz measuring speed and integrated controller with Ethernet interface

Micro-Epsilon has launched the optoNCDT 2300, a high-end, self-contained laser displacement sensor that requires no separate controller and which provides an extremely high-measuring speed of up to 50 kHz. This means the sensor is ideal for high-speed dynamic applications such as vibration measurement and uneven, rapidly changing surfaces.
Although competing sensors in the market claim to offer similar measuring rates and resolution, the new optoNCDT 2300 is the only sensor that offers a 50 kHz measuring speed and an integral controller. As Chris Jones, Managing Director at Micro-Epsilon UK Ltd states: “This really is a step change in laser sensor performance. Whilst there are a few other competing sensor manufacturers who claim to offer laser sensors with similar measuring speeds and resolution, the high resolution is only achieved by applying a high averaging factor, which then reduces the dynamic speed of the laser. The optoNCDT 2300 achieves high resolution and high measuring speeds without any averaging”.
The optoNCDT 2300 uses Micro-Epsilon’s new advanced real-time surface compensation (A-RTSC) technology, which enables the sensor to automatically compensate in real time for difficult-to-measure surfaces. A-RTSC is a further development of Micro-Epsilon’s patented RTSC feature, which, when combined with high-speed software algorithms, dramatically reduces signal noise at high-measurement speeds. When users need to measure against a shiny surface, for example, they ideally require a sensor that is able to automatically adjust the laser pulse duration (or laser on time) of the sensor to give them the optimum exposure time on the CCD for that particular surface. This, in turn, provides a higher accuracy measurement due to lower noise level on the output signal.
The optoNCDT 2300 laser triangulation sensor is available in five models with measuring ranges from 2 mm up to 100 mm. Resolution is up down to 0.1 μm and linearity is down to ±0.4 μm. Data output are via Ethernet, RS422 or EtherCAT. The sensor is also extremely compact, measuring just 80 mm by 75 mm by 30 mm.
Another added feature of the optoNCDT 2300 is that the sensor can now be configured remotely by using a web browser interface. This direct connection means the user can store parameters for a particular application, which can then be uploaded to one or multiple sensors, reducing set up time considerably.
In order to measure the thickness of transparent materials such as plastics, there is now no need for a second sensor unit to be installed. The optoNCDT 2300 records the first and second reflection from the target surface.
