Motion sensor ORNO OR-CR-240 5.8 GHz ultra-flat 360° IP20 2000W

ORNO OR-CR-240 is an ultra-flat microwave motion sensor that operates at 5.8 GHz and provides 360° detection coverage for indoor installations. With IP20 protection and a maximum switching capacity of 2000 W, the device is intended for ceiling- or wall-mounted presence detection to control lighting and other electrical loads automatically. The compact design and wide detection angle make it suitable for areas where discreet, reliable motion sensing is required.

Advantages

The sensor combines microwave technology with an ultra-flat housing to deliver stable detection regardless of ambient light conditions. Its 360° coverage ensures a broad detection zone while the 5.8 GHz frequency reduces susceptibility to common sources of interference. Rated for up to 2000 W switching, the unit supports a variety of lighting types and electrical loads. IP20 protection means the sensor is suitable for indoor environments and simple installation on ceilings or walls.

Suitable for (tasks / use cases)

• Corridors and hallways with continuous pedestrian flow
• Stairwells and landings where automatic lighting is needed
• Offices and meeting rooms for presence-based lighting control
• Utility rooms, storage areas and technical spaces requiring occasional occupancy detection

Key specifications

• Detection method: microwave (Doppler) at 5.8 GHz
• Detection coverage: 360°
• Mounting: ceiling or wall, ultra-flat profile
• Protection rating: IP20 (indoor use)
• Maximum switching capacity: 2000 W

How to use

Install the sensor on a suitable indoor surface—ceiling or wall—at the recommended mounting height for optimal 360° coverage. Connect the device to the controlled lighting or load circuit following local electrical regulations and ensure power is disconnected during installation. After wiring, power up the circuit and verify detection by walking through the coverage area. Adjust mounting position as needed to avoid dead zones and to align the detection pattern with expected movement paths.

Usage recommendations

For reliable performance, avoid installing the sensor near large metallic objects or equipment that may reflect microwave signals. Use the sensor indoors in dry environments and ensure ambient conditions match IP20 requirements. When controlling sensitive electronic loads, confirm compatibility with the sensor's switching capacity and consider adding appropriate inrush current protection if required.
