This switch is based on infrared technology, it will automatic turn on when the sensor detects the change of the infrared spectrum of the human body in the sensing range. High and stable sensitivity, automatic turns on/off depended on people's motion. Friendly and convenient, safe and energy-saving.Features:1. When pedestrians into the sensing range light will start automatically, when they leave light will delay and shut down automatically.2. With light-sensitive control, it will not turn on the light during daytime or strong light conditions, or it can be set to turn on the light any environment.3. It opens in the delay period, if there is no human activity, it has the function of freely adjusting the delay time within the appropriate range.4. With effective LED fault indication for easy installation and failure analysis.5. Built-in temperature compensation chip to reduce the sensing distance affected by temperature.Specification:Condition: 100% Brand NewItem Type: Motion Sensor SwitchMaterial: ABSColor: WhiteFunction: Relay control loadWorking Voltage: 12V DCOperating Temperature: -20 °C - +50 °CStatic Power Consumption: 0.05W (220VAC)Load Power: 800WLoad Capacity: All kinds of weak electric lighting, all kinds of weak electricity monitoring equipmentWiring Method Input: 12VDC output 12VDC (can be dry contact output)Output Mode: Inductive outputLight Control Range: 5Lux - 500Lux ± 20% (inductance adjustable)Delay Range: 30-350Secs ± 30% (delay adjustable)Induction Method: PassiveInduction Angle: 360° cone angleSensing Distance: Approx. 5 - 7m / 16.4 - 23ftInstallation Method: Suction point installation / Ceiling installationSize: Approx. 89 x 36mm / 3.5 x 1.42inPackage List:1 x Infrared Motion Sensor Switch2 x Screw2 x Green Expansion Tube3 x Red Expansion Tube1 x ManualNote:1.
