Thanks to its advanced optical system, the measured values can be read out with 16-bit resolution and can thus go all the way down to 0.06 µm. Thanks to proven algorithms, stable measured values are obtained even for surfaces that are difficult to measure, for example sheet metal with speckle effect, and can be evaluated reliably.
The measured value demonstrates exceptional accuracy. Relative to the entire measuring range, maximum linearity error amounts to just 0.05 %. With a maximum range of 1,000 mm, the PNBC sensors are amongst the most accurate products on the market. Besides high accuracy, they also offer high measurement speed: With measuring frequencies of up to 30,000 Hz, the PNBC sensors are well above average relative to comparable distance sensors.
Minimized temperature drift makes use of the sensor possible immediately after switching it on without a long warm-up phase, and the sensor can get down to work without delay. The measured value is read out simultaneously via the analog output and the Ethernet TCP/IP interface – the latter makes the sensors compatible with the requirements of Industrie 4.0 applications, providing users with the opportunity of forwarding data to higher-level system participants directly via network integration.
What’s more, the sensors are also equipped with up to four switching outputs which can be used, for example, as incremental encoder inputs or for switching emitted light on and off. Beyond this, diverse sensor setting options are made available by separate Wenglor software (wTeach). In particular, the software is well suited for diagnostic purposes, i.e. checking temperature or signal strength.
