Mechanical safety and reliability are particularly important for safe encoders. The DFS60S Pro encoder fulfills the strictest test criteria and is a safety product certified up to SIL 2 or PL d. The DFS60S Pro supports the safety functions defined in IEC 61800-5-2 and guarantees first-class quality and absolute precision – in every detail. It boasts a precise optical scanning system and a high mechanical load capability.


Mechanical reliability - thanks to safety clamping ring with positive and non-positive connections

Successfully tested by the Institute for Occupational Safety and Health of the German Social Accident Insurance (IFA)

Mechanical reliability - solid shaft flattened or with feather key groove

Its electronic and mechanical design ensures certified safety levels, every time.


Implementation is easy because with the DFS60S Pro, safety functions for stationary and mobile safety applications can be made available in next to no time. The significantly reduces time and costs for implementation. Particularly when the encoder is combined with safety products from SICK (optional). This is very easy to set up using the plug and play principle and gives you the benefit of coordinated safety products. It's the ideal solution for ensuring the safety of people, machines, and systems.
