Motion sensor ORNO OR-CR-253 360° IP20, 2000W, 3 sensors, adjustable range 3–20 m, white

ORNO OR-CR-253 is a 360° indoor motion sensor designed for automatic switching of lighting and other electrical loads up to 2000 W. The device has three sensing elements that improve detection coverage and an adjustable detection range from 3 to 20 m, allowing tailored installation for corridors, stairwells, storage areas and commercial interiors. With an IP20 rating it is intended for indoor use and delivers hands-free operation where timed or presence-based switching is required.

Advantages

The triple-sensor design increases detection reliability across a wide angle, reducing missed activations in multi-directional traffic areas. Adjustable sensitivity and range make it possible to adapt the sensor to different room sizes and mounting heights. A high maximum load capacity enables direct control of lighting circuits without the need for additional relays in many installations. The compact white housing integrates into interiors with minimal visual impact.

Suitable for

• Corridors and hallways in residential and commercial buildings
• Stairwells and landings
• Storage rooms, utility rooms and cleaning closets
• Office entrances, reception areas and back rooms

Key specifications

• Detection angle: 360° coverage
• Detection elements: three sensing units for improved coverage
• Detection range: adjustable from 3 m to 20 m
• Maximum switching capacity: 2000 W
• Ingress protection: IP20 for indoor environments
• Color: white housing suitable for discrete interior mounting

How to use

Install the sensor according to local electrical codes and mount it at the recommended height for the planned detection range. Adjust the detection range control to set the required coverage between 3 and 20 m and verify detection by walking through the monitored zone. Connect the sensor in series with the lighting or load circuit, ensuring the total connected load does not exceed the maximum switching capacity. After installation, perform a test sequence to confirm reliable operation and adjust sensitivity or range as needed.

Usage recommendations

For optimal performance, position the sensor so that primary traffic paths fall within its 360° coverage and avoid direct exposure to HVAC vents or reflective surfaces that may cause false triggers. When controlling high inrush loads or motorized equipment, use an appropriate relay or contactor to protect the sensor from excessive switching currents.
