Wenglor releases high-performance sensors

Reliable measurement of extremely small components in the micron range often pushes optical sensors beyond their limits.

Now with the introduction of its new PNBC range, Wenglor is setting new standards in accuracy with their maximum resolution of 0.06μm with only 0.05% linearity error. This impressive precision is supported by excellent reproducibility and thermal stability – even at output rates of up to 30kHz.

Wenglor’s new range of PNBC sensors work with a high resolution CMOS line array and determine distance to the object by means of angular measurement.

Top quality optics make measured values possible which can be read out with 16-bit resolution and can thus go all the way down to 0.06μm.

Thanks to proven algorithms, stable measured values are obtained even for difficult to measure surfaces, for example sheet metal with speckle effect, and can be reliably evaluated.

With a maximum range of 1000mm, PNBC products are amongst the most accurate sensors available on the market and with measuring frequencies of up to 30,000Hz, PNBC sensors are well above average relative to other, comparable distance sensors.

Minimised 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 Industry 4.0 compatible Ethernet TCP/IP interface. This provides users with the opportunity of forwarding data to higher-level system participants directly via network integration.

The new sensors are equipped with up to four switching outputs, which can also be used as incremental encoder inputs or for switching emitted light on and off.
