Classification: CPC F  G  B | IPC B  G

Claim 0:
1. A sensor system comprising first optoelectronic distance sensors for monitoring a hazard zone at a movable machine part having at least one protected field,
wherein the first optoelectronic distance sensors are arranged in annular form in a first ring at the movable machine part,
wherein at least one of a tool and a workpiece is arranged at the movable machine part,
wherein optical axes of detection beams of the first optoelectronic distance sensors each extending at an acute angle from a tangent to the annular form,
wherein second optoelectronic distance sensors are arranged in annular form in a second ring at the movable machine part, wherein the first optoelectronic distance sensors have optical axes positioned at an acute angle with respect to a center axis of the movable machine part so that a frustoconical protected field is formed,
and wherein the first optoelectronic distance sensors have additional optical axes aligned radially outward from the first ring in parallel with a plane of the first ring.
