Abstract
Light barrier apparatus arranged in a housing comprises at least one photoelectric converter, at least one front lens arranged in a wall of the housing, an electronic circuit connected to the photoelectronic converter(s), power supply lines leading from power supply terminals to the electronic circuit, and also, in the case of a receiver or a transmitter/receiver signal lines and signal terminals. The housing is subdivided into first and second housing parts (11, 12) which are pivotably connected together by an articulated coupling (15). The first housing part (11) contains, at least in large part, the electronic circuit including the power supply lines, power supply terminals and, if present, the signal lines and signal terminals. The second housing part contains at most a part of the electronic circuit, the electronic converter and also the front lens. The articulated coupling between the first and second housing parts has a passage (16) for accommodating the connecting lines (19) between the first and second housing parts (11, 12) (FIG. 2).
