DBS50E-S5RK01000

The SICK DBS50E-S5RK01000 is a high-performance, bearingless absolute encoder from the robust DBS50 series. It is engineered to provide highly accurate rotational position and speed feedback by utilizing the existing bearings of a machine's shaft, eliminating the need for its own internal bearings and the associated maintenance or alignment issues.
