Abstract
A light grid () is provided having a plurality of light transmitters () for transmitting a respective monitoring light beam () and having a plurality of associated light receivers () to generate an objection detection signal (-) depending on the reception of the monitoring light beam, having a control () which is configured to divide the monitoring light beams () into groups and to consecutively activate the monitoring light beams () of the groups, wherein, in a group-wise parallel monitoring sequence, a respective monitoring light bream () of each group is activated in parallel, as well as having a first bus () over which the object detection signals can be output to the control () by the light receivers (). The light receivers () are in this respect configured to output the object detection signals to the control () in a time multiplex process.
