Unlike incremental rotary encoders, absolute rotary encoders can output the exact position value immediately, without referencing, and without movement of the encoder shaft.The innovation: Vernier measurement methodA unique characteristic of the Lenord + Bauer magnetic absolute rotary encoders is the Vernier measurement method, which offers a particularly high resolution of up to 16 bit in single turn, or 28 bit in multiturn operation (65,536 steps per revolution). Motion processes are acquired with an accuracy of 0.08°, and are output in a reproducible signal quality.This is possible because they are scanning a ferromagnetic code disc in the sensor housing. The code disc features three tracks, each with different contour numbers. As soon as the absolute rotary encoders are connected to the power supply, the absolute position can be precisely determined by means of the distinct phase offset between the three tracks.Robust sensors withstand temperature fluctuations, humidity, and vibrationTogether with their high level of accuracy, the magnetic absolute rotary encoders from Lenord + Bauer have the big advantage of providing exact measurement data even under changes in ambient temperature, fluctuations in humidity, strong vibrations, or condensation.Due to their robust design, they are frequently used for speed and position acquisition in wind turbines or mobile machines.Flexible bus cover system offers a variety of digital and analogue interfacesDue to a flexible bus cover system, the rotary encoders with integral bearings are optionally available with: Synchronous serial interface (SSI) EtherCAT PROFIBUS-DP 0 to 10 V 4 to 20 mAAlternatively, Lenord + Bauer offers the absolute rotary encoders also with integrated interfaces.
