Safety encoders

Safety encoders from SEW‑EURODRIVE are characterized by their exceptional reliability as well as electronic and mechanical load capacity.

Safety encoders allow you to improve the safety of your machines by implementing safety functions in relation to their speed, direction of rotation, idle state, relative position, or absolute position. The safety encoder provides the safety-relevant signals in the intelligent interaction of sensor, control, and actuator.

The safety function requires a reliable mechanical connection between encoder and motor. At SEW‑EURODRIVE, this connection is dimensioned in such a way that fault exclusion is achieved.

The safety encoders cannot trigger a safe state at the machine autonomously. Therefore, they have to be monitored in the overall system. In case the encoder or the evaluation electronics detects a fault, a fault response, such as safe state, is initiated in the overall system.
