The Lutron LRF3-OCR2B-P-WH is a battery-powered wireless occupancy and vacancy sensor that brings intelligent automation to lighting systems without the need for wiring. Designed to mount on ceilings in residential or commercial spaces, it uses passive infrared (PIR) motion detection to sense when areas are occupied and then signal compatible lighting or dimming devices to turn lights on or off automatically.

Thanks to Lutron’s Clear Connect® RF wireless technology, this sensor communicates reliably with compatible loads — making it simple to retrofit into existing Lutron systems including RA2 Select, Maestro Wireless and RadioRA-SR setups. Its auto-on, low-light threshold and manual-on modes give flexibility in how and when lights are activated, helping to save energy and improve convenience.

Ideal for areas such as hallways, offices, meeting rooms, or utility spaces, this ceiling-mounted sensor provides hands-free lighting control that enhances comfort and safety while reducing energy waste.

Three Reasons Customers Recommend This Product

1. Hands-Free Lighting Control: Users appreciate how the sensor automatically turns lights on when motion is detected and off when spaces are vacated, improving convenience in everyday use.
2. Smart Low-Light Mode: The Auto-On Low-Light feature ensures lights only switch on when needed — such as in dim conditions — reducing unnecessary energy usage.
3. Easy, Wireless Installation: Because the sensor is battery powered and wireless, it installs quickly on ceilings without new cabling — a major benefit for retrofits or upgrades.

How It Works

The Lutron LRF3-OCR2B-P-WH uses passive infrared (PIR) motion technology to detect changes in heat patterns caused by people moving within its coverage area. When motion is sensed, it sends a wireless RF command (via Clear Connect® technology) to linked dimmers, switches or control modules to turn lighting on or off according to the selected mode. The 360° field of view and configurable modes make it suitable for many indoor spaces.
