Abstract: The invention relates to a sensor for detecting objects in a monitoring area. The sensor has a display unit that is comprised of a series of lamps with a linear arrangement of lamps. The series of lamps is arranged around an axis of rotation running parallel to its longitudinal axis and rotates at a specific rotary speed. The series of lamps is controlled via a control unit in such a way that the columns of a matrix-type display field to be presented at a clock rate of the display field are individually output one after the other to the series of lamps and displayed with it. The clock rate is adapted to the rotary speed in such a way that these displays complement one another to form a standing image of the display field. The sensor is a safety sensor.
