Abstract:
The present invention relates to a light barrier for the monitoring of a light path having a base assembly of a first transmitter emitting a light signal and a first receiver generating an output signal for a control. In accordance with the invention, the light barrier has an active reflector assembly having a second receiver for the reception of the light signal emitted by the first transmitter and a second transmitter for the transmission of a feedback signal in dependence on the received light signal.
