Abstract
The present invention relates to a safety photoelectric barrier for monitoring a protective field and to a corresponding method. A safety photoelectric barrier () comprises a single-sided transceiver bar with a housing (), a plurality of transceiver modules () each having a radiation emitting unit () for emitting radiation towards a reference target (), a radiation detecting unit () for detecting radiation incident on the transceiver module (), and a signal processing unit for evaluating the detected radiation regarding a distance information and an intensity information and for generating a binary output signal indicating the presence or absence of an object within the protective field. A controller module () evaluates the binary output signals and generates a safety signal in response to the evaluated output signals. The radiation detecting unit comprises at least a first and a second photosensitive element () for redundantly evaluating the distance and intensity information.
