| Zusammenfassung: | A light curtain system (70) for sensing the intrusion of objects into detection planes which define a protected zone. A plurality of light curtain segments (72,74) are provided with each segment including spaced-apart transmitter (76,78) and receiver heads (80,82). The transmitter and receiver heads are each connected in series by flexible cables which form a part of a control circuit. The series-connected segments permit the detection planes to be aligned in predetermined angular orientations as required by the particular application. |
