## Long description

The ORNO OR-CR-239 recessed microwave motion sensor operates at 5.8 GHz and provides a 180° detection angle for reliable presence detection in indoor spaces. Designed for recessed installation, this sensor offers automatic switching of lighting and other loads up to 1200 W and uses microwave reflection to detect motion through small obstructions, ensuring prompt response in corridors, offices, stairwells and utility rooms. With an IP20 rating it is intended for indoor environments where protection against solid objects is sufficient.
Advantages
The sensor delivers wide-angle coverage and precise microwave detection that is less affected by ambient light conditions compared with purely optical detectors. Recessed mounting ensures a discreet appearance and reduces the chance of accidental damage. A high switching capacity supports a variety of lighting types and other electrical loads up to 1200 W, while the 5.8 GHz frequency provides stable detection sensitivity and reliable performance in typical indoor environments.
Suitable for
 Automatic lighting control in corridors and hallways
 Office lighting and space occupancy detection
 Stairwells and landings where hands-free switching is required
 Utility rooms, storage areas and technical spaces
Key specifications
 Operating frequency: 5.8 GHz
 Detection angle: 180°
 Installation type: recessed mounting
 Protection rating: IP20 (indoor use)
 Maximum switched load: 1200 W

How to use
Install the sensor into a compatible recessed housing or ceiling fixture at the recommended height and orientation to achieve the specified 180° detection coverage. Connect wiring according to local electrical standards and ensure the load does not exceed 1200 W. After installation, adjust the sensor position or any available sensitivity settings so the detection zone aligns with the intended coverage area. Verify operation by walking through the monitored zone and confirming that lighting or connected loads switch on and off as expected.
Usage recommendations
For reliable performance, mount the sensor in a stable indoor location free from large moving metal objects and avoid placing it directly behind thin metal screens. Regularly check connections and the load rating when changing fixtures. Use the sensor in applications where IP20 protection is appropriate and follow local wiring regulations during installation.
