The finding concerns an integrated device for the detection and indication of obstacles for a motorised system of gates and the like, which comprises at least one transmitter (3) and a receiver (4) of an infrared signal (5), arranged on the outer sides of the access opening (1) controlled by the gate (2) or the like and indicating to the control unit of the actuator (6) of the gate when said signal is blocked by an obstacle; said transmitter (3) and receiver (4) comprise at least one flashing luminous indicator light, activated during the opening and closing steps. Such a device is characterised in that the activation of the indicator light of the receiver element (4) is controlled by receiving the infrared signal from the transmitter (3) coupled with it ( fig.1 ). |
