Improved safety device (1), particularly for equipment in movement such as automatic gates (3) and the like, comprising a mobile element (2) provided with at least one sensitive edge (4) electrically connected to a control panel (5) by means of an electric circuit; said device being characterized in that said electric circuit comprises said mobile element (2) with conductor function. This device (1), unlike the devices of known type, allows the installation and the connection of safety edges without the use of spiral cables, festoon cables, cable-carrier chains, systems via radio and/or optical systems, such as infrared, with the consequent aid of batteries which in the short and long term lead to considerable problems of reliability, maintenance and quick wear. |
