The Speed Monitor is a zero-speed drive monitor that protects against dangerous movements by safely monitoring speed. It has different safety drive functions, such as SLS (safety limited speed) and SSM (safe speed monitor). In addition, the MOC3SA offers different operating modes: one mode with two independent proximity sensors, or a mixed mode with oneproximity and one signal output. The Speed Monitor is connectable to all SICK safety controllers.
