DBS50E-S5RK01024

The SICK DBS50E-S5RK01024 is a high-resolution, solid-shaft incremental encoder from the DBS36/50 series, designed for robust and precise industrial motion control. It features an 8-mm diameter stainless-steel shaft with a face-mount flange and provides reliable position feedback via incremental (open-collector) signals. With 1,024 pulses per revolution (PPR), it delivers fine-grained feedback for demanding automation environments.
