Motion sensor ORNO OR-CR-208 5.8 GHz microwave 360° detection up to 1200 W white, 3–2000 lx

ORNO OR-CR-208 is a 5.8 GHz microwave motion sensor providing 360° presence detection and designed to control lighting and electrical loads up to 1200 W. With adjustable ambient light sensitivity from 3 to 2000 lx, the sensor can operate selectively during day or night conditions and detects movement across its coverage area to trigger switching. The compact white housing is suitable for ceiling or wall mounting in indoor environments such as corridors, stairwells, storage rooms and service areas.

Advantages

The microwave technology ensures reliable motion detection with penetration through non-metallic obstacles and stable performance in varied temperature and humidity conditions. A wide sensitivity range for ambient light allows precise control to avoid unnecessary switching during daylight while maintaining responsiveness in low-light situations. The 360° detection pattern maximizes coverage from a single mounting point, reducing the number of devices required for continuous monitoring. The unit supports switching of higher-power loads up to 1200 W, which makes it compatible with a variety of lighting types and installations.

Suitable for

• Indoor corridors and hallways
• Stairwells and landings
• Storage rooms and utility areas
• Service rooms, basements and technical spaces

Key specifications

• Detection frequency: 5.8 GHz microwave
• Detection angle: 360° coverage
• Switching capacity: up to 1200 W
• Ambient light sensitivity: adjustable from 3 lx to 2000 lx
• Mounting: ceiling or wall, indoor use
• Color: white

How to use

Mount the sensor on a ceiling or wall at the recommended height and orientation to obtain full 360° coverage of the monitored area. Adjust the ambient light sensitivity to the desired threshold so the sensor only activates lights when illumination falls below the selected lux level. Connect the load according to wiring instructions for the installation, ensuring the connected lighting or equipment does not exceed the maximum switching capacity. After installation, test the detection area by walking through different zones to confirm coverage and fine-tune sensitivity settings if necessary.

Usage recommendations

For reliable operation, avoid installation near large metal objects or inside fully enclosed metal housings that can reflect or absorb microwave signals. Position the sensor away from heat sources and direct airflow from HVAC outlets. Regularly verify the ambient light threshold to match seasonal lighting changes and check connections if load switching is inconsistent.
