Abstract
A device for contactless detection of glass sheets in movement in glass installations, using a reflective photoelectric barrier, includes an emitter and a receiver (3) of light beams (4). The light beams follow a path in a channel (6) of heat-resistant material whose walls delimit a homogeneous isothermal environment, the channel emerging in the vicinity of sheet (11) to be detected.
