## Long description

The Ultrasonic motion and presence sensor ORNO OR-CR-275/W offers 360° detection in a slim 2.5 cm housing designed for indoor use. This device combines motion and presence sensing based on ultrasonic technology, enabling reliable detection of moving and stationary occupants. With IP20 protection and support for loads up to 2000W, it is suitable for direct control of lighting circuits and energy management systems in offices, corridors and residential rooms where discreet, low-profile installation is required.
Advantages
The ultrasonic detection provides consistent sensitivity to motion and presence, including small movements that infrared sensors may miss. The full 360° coverage minimizes dead zones and allows flexible placement on ceilings. The ultra-slim profile facilitates unobtrusive installations in suspended ceilings and shallow mounting locations. Rated for up to 2000W load capacity, the sensor can directly switch many lighting types while IP20 rating confirms suitability for protected indoor environments.
Suitable for
Ceiling-mounted lighting control in office open-plan areas
Corridor and stairwell occupancy detection
Residential rooms such as living rooms, hallways and utility rooms
Energy-saving automation and timed lighting systems
Key specifications
Detection technology: ultrasonic motion and presence sensing
Detection angle: 360° coverage
Mounting: ultra-slim ceiling installation, 2.5 cm profile
Ingress protection: IP20 (indoor use)
Maximum switching load: up to 2000 W
Application environment: indoor commercial and residential spaces
How to use
Install the sensor on a ceiling surface at a recommended position that provides unobstructed coverage of the monitored area. Connect the device into the lighting circuit following local electrical regulations and ensure the load does not exceed the specified maximum switching capacity. After power-up, verify coverage area by observing the controlled lighting response to typical movements and adjust installation placement if necessary. For presence detection of stationary occupants, allow a brief settling period as ultrasonic sensing calibrates to the environment.
Usage recommendations
Place the sensor centrally in the monitored zone and avoid mounting near large moving machinery or HVAC vents that can cause false triggers. Use the sensor in indoor dry environments and ensure wiring and installation are performed by a qualified electrician to maintain safety and compliance with local codes.
