Product overview A ceilingmounted microwave motion sensor switch that turns lighting on automatically when movement is detected. Designed for indoor ceiling installation, it uses a 5.8 GHz microwave detector and an adjustable photosensor to prevent activation in daylight if required. Available in three models and delivered in white. Key benefits Energy efficient automatic lighting control that reduces wasted run time. sensitivity microwave detection for reliable activation when people enter the coverage area. Adjustable sensing distance, time delay, and light level settings for flexible installation and operation. Compact ceiling mount design for easy retrofit in corridors, stairwells, offices, storage rooms, and utility spaces. Main features Detection method: 5.8 GHz microwave CW motion sensing with 360 degree coverage. Builtin photosensor with adjustable Lux threshold to disable activation during daylight or allow 24 hour operation. Adjustable time delay and sensing distance for customized response. Simple indoor ceiling installation. Color: White. Package includes: 1 light switch sensor. Model options and specifications 1) SK807KDC Power: 12 to 24 V DC. Frequency: 5.8 GHz +/ 75 MHz CW.

Package weight: approx. 133 g. Installation and operation notes Install on indoor ceilings where 360 degree coverage is required. Use the photosensor setting to prevent activation during daylight or to allow night only triggering. Adjust sensing distance and time delay to avoid false triggers in traffic areas or to maintain illumination for occupied spaces. Ensure wiring matches the selected model power requirements: DC for SK807KDC or AC 110240 V for SK600 and SK700. Typical applications Corridor and stairwell lighting that requires automated on off control. Office common areas and meeting rooms for hands lighting. Storage rooms, utility rooms, and restrooms where occupancy based control reduces energy use. What is included 1 x ceilingmounted microwave motion sensor light switch.
