Motion sensor ORNO OR-CR-270/W, 2- and 3-wire, 190° detection, IP65, 500W, max 20 m range, for flush box, white

ORNO OR-CR-270/W is a compact ceiling or wall-mounted motion sensor designed for lighting and security automation in indoor and sheltered outdoor environments. The device supports selectable 2- or 3-wire connections, provides a wide 190° detection angle and is rated for an IP65 protection level. With a maximum switching capacity of 500 W and a sensing range up to 20 m, it is intended for installation into a standard flush electrical box and finished in white for discreet integration.

Advantages

The sensor offers flexible wiring options to suit existing electrical installations and a wide detection angle to cover large areas with a single unit. Its IP65-rated enclosure protects against dust and low-pressure water jets, enabling use in protected outdoor locations as well as indoor spaces. The flush-box mounting provides a neat, low-profile appearance and the white finish blends with common ceilings and walls.

Suitable for

• Corridors and stairwells in residential and commercial buildings
• Indoor utility rooms, garages and basements
• Covered outdoor entrances, porches and carports
• Small retail areas and service zones requiring automated lighting control

How to use

Install the sensor into a compatible flush electrical box following local electrical codes and switch off power before wiring. Select the required 2- or 3-wire configuration according to the load and circuit type. Secure the unit to the box and restore power, then test detection by walking through the coverage area. Adjust the sensor position within the box and any available sensitivity settings on the device or wiring to achieve the desired coverage and response for lighting or security automation.

Usage recommendations

Position the sensor centrally in the area to be monitored for optimal coverage, avoiding direct exposure to rain or heavy spray despite the IP65 rating. Use the 3-wire option when a neutral is available and required by the load, and the 2-wire option for simple switching circuits. For reliable performance, avoid mounting near heat sources, large moving objects or glass surfaces that may affect detection range.
