The advanced optical sensor uses infrared light to detect water hitting its surface. This method of
detection is more sensitive and reliable than other methods, is nearly immune to false detection, and
is not affected by movement and most environmental conditions.
The Phason Rain Sensor's durable and rugged enclosure is completely sealed, so there are no
electronics to corrode, and no openings for debris to collect.
Power contactors
Phason’s 240-volt power contactors are heavy-duty relays that increase the load handling capability
of control relays. Power contactors are ideal for electric heaters.

contactor relay and mounting hardware for easy
mounting in an enclosure.
Power contactor kit
