Renkforce RF-4216076 Flush mount HF motion detector 180 ° Relay White IP20

The sensor works with high-frequency technology transmitting an inaudible signal able to penetrate doors, glass panels and thin walls. Due to its wide detection angle (180°) and range (5-15m), this senor is ideal for a huge variety of areas, staircases and complex room layouts regardless of the temperature in the monitored area.The motion sensor can be activated by ambient light ranging from 3 to 2000 lux, with a time delay between 10 seconds and 12 minutes. This high-quality sensor has been specially designed for resistive loads of up to 1200W, and inductive loads of up to 300W. Using the sensor to automatically switch on and off appliances frees up plenty of time.
