The absolute measuring system at 986 ..4026 rotations eliminates the need for time-consuming reference runs and increases the efficiency of the machine. Direct measurement of the position ensures highly accurate positioning. The galvanically separated supply voltages for the control and performance electronics permit the implementation of an emergency shut-off function without interrupting communication with the control module.

The PSD can be easily addressed by rotary switches (not for IO-Link). The instruments can be mounted on a spindle using the hollow shaft without the need for an additional coupling. The direct drive is also available in vertical design (PSD 41). The optional rotatable attachment housing allows you to attach the direct drives to the machine in any position, no angle plugs are required.
