In brief: A wind sensor measures wind speed or the movement of the awning and retracts it automatically when the wind is too strong. A sun sensor extends it in sunshine. With a radio awning motor, the sensor is simply paired; cable motors need a control unit.
Sensor types
| Sensor | Function | Mounting |
|---|---|---|
| Wind sensor (cup anemometer) | measures wind speed | on the façade or awning bracket |
| Motion or vibration sensor | detects vibrations on the front profile | directly in the front profile, wireless |
| Sun sensor | extends in bright light, retracts when cloudy | usually combined with a wind sensor |
With radio motor
The A-OK AM45E ist mit eingebautem Funkempfänger (433 MHz) erhältlich und lässt sich mit Wind- und Sonnensensor kombinieren. Zusätzlich hat er eine Nothandkurbel – die Markise lässt sich auch bei Stromausfall einfahren.
With cable motor
With a cable motor such as the A-OK AM45 mechanical the sensor needs a control unit that switches the motor. The wind command always has priority over the push button.
Setting the threshold
Set the wind threshold rather low – better retracted once too early than a bent folding arm. Observe the awning manufacturer’s specifications on permissible wind load.

Frequently asked questions
Does the awning retract during a power cut?
No – the sensor needs power. With the AM45E, the awning can be cranked in by hand.
Can I retrofit a sensor without running cables?
Yes, with a radio motor and a radio-based sensor.
