Lenord + Bauer Absolute Rotary Encoder

A 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.
