Displacement sensor maintains full sensitivity at reduced span

Replacing the optoNCDT 1401 sensor, the optoNCDT 1402 laser sensor is a new addition to Micro-Epsilon's optoNCDT 1400 series. The 1402 offers enhanced performance and additional flexibility in terms of adjusting the measuring range while maintaining the full output span.

A new 'teach-in' facility enables users to limit the measuring range to suit different measurement tasks. For example, the measuring range of a 200mm sensor can be reduced down to 165mm in order to suit the application. In doing this, the user still benefits from a full output span (4-20mA, 1-5V, RS422), which maximises the sensitivity of the sensor. With previous sensors in the 1400 range, the user would get a reduced output if the measuring range were decreased in this way.

The 1402 has an integral controller that automatically compensates in real time for difficult-to-measure surfaces such as shiny metal, gloss paint finishes and black rubber. This real-time surface compensation (RTSC) feature enables OEMs and machine builders to measure more accurately a variety of object parameters, including thickness, roundness, position, deflection, tilt, displacement and vibration. The 1402 can also be used for online and offline quality inspection, dynamic part profiling and part recognition.

High performance yet cost-effective

Chris Jones, Managing Director at Micro-Epsilon (UK), comments: "The 1402 is unique in terms of offering the customer a high-performance, cost-effective laser displacement sensor that is able to compensate for changing surfaces in real time and has the flexibility to allow the user to adjust the measuring range to suit their individual task. An increased measuring rate of 1.5kHz also means the sensor can easily cope with very fast, inline production, assembly or quality inspection tasks."

Thanks to its integral controller and compact design, rapid mounting and installation is easy, even in restricted spaces on machines or next to production lines. With no separate controller to mount, machine builders and systems integrators will reduce associated wiring costs and free up space in their control cabinets.

A swivelling cable connector on the optoNCDT 1402 sensor makes it possible to change the direction of the cable output to suit the application. The sensor offers an analogue current/voltage output and an RS422 digital interface.

The new optoNCDT 1402 series comprises seven sensors with measuring ranges from 5-250mm.
