1. Wide Range Of Sensing, Low Impact Of High Temperature, Hidden Installation, Penetrating Sensing 2. Sensing The Change Of Object Displacement Is Different From The Human Body Sensor Switch, Which Mainly Senses The Change Of Infrared Rays. When The Ambient Temperature Is High, It Is Difficult To Distinguish And The Distance Becomes Closer. The Microwave Radar Sensor Switch Is Not Affected 3. Penetrating Sensing, Can Penetrate Plasterboard/Glass/Plastic/Acrylic/Wooden/Thin Wall, Etc., And Can Be Installed Hidden In The Lampshade. Cannot Penetrate Metal Plates 4. Long Distance, Wide Range, 4-16 Meters Multi-Level Sensing Distance Adjustable, Higher Sensitivity Than Infrared Sensing 5. It Can Be Installed Hidden In The Lampshade, Keeping The Layout, Hidden Installation, Built-In Ceiling Lamp, Hidden By Plaster Ceiling Working Voltage: 220VAC (50Hz) Product Model: -WB60(Three-Wire System) Induction Angle: Angle 30-170 Standby Power: About 0.6W Delay Time: 2s-20 Minutes (Six Gears Adjustable) Sensing Mode: Sensing Object Displacement Installation Height: Ceiling 3-5m/ Wall 1.5m Installation : Hidden Installation Sensing Distance: 1-16m (Four Gears Adjustable) Microwave Power: Less than 1mW (Mobile Phone Radiation 0.1%) Different batches may have differences in product appearance, color, and characters, which will not affect the use Colour:white Material:ABS Size:4.1 x 7.5 x 2.75cm Package Contents: 1 x LED Radar Sensor Only the above package content, other products are not included.
