Kemo M152K Capacitive Rain Sensor, Relay Activation Even with Distilled Water, Adjustable Sensitivity, with 2 LED Indicators

M152K When the fully insulated sensor plate gets wet (e.g. rain drops), then turns on a relay. Unlike rain detectors with a metal sensor, this sensor works in a capacitive manner. This means that it switches on even when it comes into contact with distilled water (in very clean rain). This allows roof windows to be closed, awnings retracted or only rain can be reported. 2 built-in LEDs show the function. The sensitivity is adjustable. Operating voltage: 12 V / DC. Power consumption: max. approx. 130 mA. Relay contact: 1 x on, max. 25 V, 2.5 A load capacity. Sensor heating: automatic when rain contact occurs. LED 1: Indicates that the rain sensor is in operation. LED 2: Indicates that rain is reported and the relay has switched on. Relay duty time: as long as the sensor is wet. Adjustable sensitivity. Active sensor surface: approx. 26 x 32 mm. Overall dimensions: approx. 65 x 45 x 36 mm.
