Recessed Microwave Presence Sensor, 5m, AC 100-240V

The SUCH recessed microwave presence sensor is a ceiling-mounted occupancy sensor designed for automatic lighting control based on real-time human presence detection. Designed to fit a 65mm ceiling cutout, it operates on AC 100-240V and provides 360° detection coverage with a maximum sensing range of 5m. Using microwave radar sensing, it is designed to detect subtle body movements and breathing-related micro-motion, helping maintain lighting operation when occupants remain seated and still. With adjustable ambient light sensitivity (3-2000 Lux) and time delay settings (10 seconds to 15 minutes), it is commonly used in offices, corridors, stairwells, restrooms, garages, meeting rooms, and other indoor lighting automation applications.

Feature

• 360° detection with a 5m sensing range provides wide-area monitoring from a single ceiling installation point, reducing blind spots and simplifying sensor placement.
• Microwave radar sensing detects subtle body movements and breathing-related micro-motion, supporting reliable presence detection even when occupants have limited movement, such as sitting at a desk.
• Ambient light threshold adjustable from 3 to 2000 Lux allows the sensor to be set for after-dark operation only, or for continuous operation regardless of daylight, depending on the installation.
• Time delay adjustable from 10 seconds to 15 minutes (±2 min) allows load hold time to be matched to how a space is used, from brief corridor transit to longer-occupancy rooms.
• Rated load up to 800W/1200W at 100V/220V (200W/600W for inductive loads) supports lighting loads within the specified power ratings.
• 65mm cutout with spring-clip mounting allows recessed installation into ceiling openings without additional surface-mounted housing.
• Operating range of -20 to +40℃ and up to 93%RH supports installation in stairwells, garages, and other indoor spaces with varying environmental conditions.
• Standby power draw of approximately 0.5W keeps idle energy consumption low while the sensor remains active.

Installation Tips

To ensure reliable detection performance, avoid installing the sensor near reflective surfaces, heat sources, or objects that may move with airflow.

• Avoid mounting near mirrors or other highly reflective surfaces.
• Keep away from heat sources such as air vents, air conditioners, and lights.
• Avoid aiming the sensor toward moving objects such as curtains or tall plants.
