Basic information OSE ensuring safety during gate use. It is mounted in the gate's rubber strip and moves with it. Information about the OSE status is transmitted to the control unit via a spiral cable. The NPN transistor output supplies ground when the beam is intact. When the beam is disturbed, the output is in a high-impedance state.Receiver (gray wire) has a yellow LED under the white seal, which is visible when the transmitter's infrared radiation reaches the receiver. The yellow wire is not used, but can optionally be used to monitor the gate's door status.
