Product Description
The large sensor surface reacts to rain or snow. The switching polarity and the sensitivity are adjustable. The
switchable heating prevents icing or condensation and accelerates drying. In the most sensitive setting, the
device is also suitable for detecting fog. The mast or wall bracket, which is available as an accessory, makes
installation easy. Typical applications are in garden centers, in agriculture, in building control systems, but also in
homes and gardens.
The rain detector is equipped with a relay contact for switching low voltages up to 30V DC/AC in order to be able
to act on switching devices such as an awning control unit. The sensitivity is adjustable over a wide range. The
device is equipped with a heater for faster drying and snow detection.
