Commutation, position and speed measurement with the corresponding number of interfaces used to require three sensors. Today, SICK motor feedback systems offer these functions in a single device. A consistent mechanical interface allows for a high level of flexibility. SICK motor feedback systems are also setting standards for electrical interfaces such as HIPERFACE® and HIPERFACE DSL®. They meet important requirements including temperature resistance, high resolution, and multiturn design. Certification to SIL2 permits implementation of the Machinery Directive as per EN ISO 13849.
