<p>A safety device for a gate or sliding door, actuated by a motor (7) is made up of a reflection photoelectric device (17), controlled by a pilot circuit, of a pressure sensitive bar (14) applied to the sliding wing (2), said bar comprising a reflector mirror, equipped with a shutter and a mobile part. Said safety system is characterized in that a force exerted on the mobile part of said sensitive bar, causes the shutter to close by intercepting the radiation (22), emitted by the transmitter of the photoelectric device (17) and stopping the reflection on the surface of the mirror in the direction of the receiver of the photoelectric device (17), sending through the pilot circuit, a signal to the control unit (8) of the actuation motor (7).</p> |
