SEGMENTED LIGHT CURTAIN SYSTEM AND METHOD |
摘要 |
A light curtain system for sensing the intrusion of objects into detection planes which define a protected zone. A plurality of light curtain segments are provided with each segment including spaced-apart transmitter and receiver heads. 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.
