The SICK DBS60E-S4AK05000 is a high-precision, bearingless absolute encoder from the DBS60 series, designed to provide accurate rotational position feedback without requiring internal bearings. This model features an extremely large 500 mm internal diameter and supports the 1 Vpp sinusoidal output (analog incremental), making it an ideal solution for velocity control applications in extra-large-scale machinery where absolute positioning is not required but high-resolution analog feedback is essential.
