Polygon Scanners

The optimal products for your polygon scanner application

Polygon scanners are based on special optics and operate, for example, sorting machines. Up to now, manufacturers had to install encoders to run these scanners with a high speed stability.

With the frequency converters by SIEB & MEYER they can do without the encoders because the devices provide a sensorless control ensuring a signal stability in the range of a few nanoseconds. This exceptional precision is reached when the frequency converter receives the synchronization signal from a facet detector. Using this principle, the operation is much more precise than with an encoder.

The integrated components of the SIEB & MEYER frequency converters are additional extras: these include, for example, a ballast circuit and resistor as well as an internal logic supply. Last but not least, the devices are very compact and require minimum space.
