Infrared technology based automatic motion sensor switch. Automatically turns on when human presence is detected and turns off after a delay when people leave. Suitable for automatic lighting in corridor, passageway, toilet, basement, warehouse, garage and other places. Brightness metering: Uses photosensitive control, does not turn on in daytime or strong light environment, and can be adjusted for induction in any light environment. Random Delay: After activation, if no human activity is detected during the delay period, the delay time operates and can be adjusted freely within 5~480s +/- 30%. Status indication: Effective induction LED indicator for convenient installation and failure analysis. Temperature compensation: Reduces the influence of temperature on induction distance. Automatic locked in daytime to save energy. Easy to install or replace existing switch. Model: -2012-DC. Working Voltage: 8-30V DC. Load: 40A. Working temperature: -20 Celsius ~ +50 Celsius. Load capacity: LED lighting (for constant voltage/constant current LED light). Sensor angle: Cone angle of 140 degrees. Induction distance: 7-10m. Colour: as shown. Material: plastic.
