Thies Clima 3.1157.10.041 | Rain Sensor, Yes/No Output, IP65
Thies Clima 3.1157.10.041 optical precipitation sensor. Detects rain presence (yes/no), 24V AC/DC supply, IP65, with heating for winter operation.
Product Overview
The Thies Clima 3.1157.10.041 is an optical precipitation sensor designed for reliable rain detection (presence/absence) in building automation and meteorological applications. It uses an infrared light barrier principle to detect raindrops on its sensing surface (~25 cm²). The sensor features a built-in heating element to prevent snow and ice accumulation, ensuring year-round operation. It provides a simple relay contact output (dry contact) to signal "Rain" or "No Rain" status, making it ideal for controlling windows, awnings, or ventilation systems.
