The OS306U‑W‑K Occupancy Sensor Switch by Cooper Wiring Devices is a high‑performance, wall‑mounted motion sensor designed to deliver automatic lighting control while improving convenience, energy efficiency, and safety in residential and commercial environments. Utilizing passive infrared (PIR) detection, the switch senses motion across a wide 180‑degree coverage field to ensure reliable activation when a space becomes occupied. The unit’s integrated intelligence automatically turns lighting ON when movement is detected and OFF when the area is vacant, dramatically reducing unnecessary energy consumption.

Engineered for flexibility, this device supports both single‑pole and 3‑way wiring, operates on 120V, and handles up to 600W of compatible lighting loads—including incandescent, halogen, LED, CFL, and fluorescent fixtures. The switch includes an adjustable ambient light sensor, user‑selectable time delay settings, a manual OFF override button, and a tamper‑resistant reinforced lens, making it suitable for high‑traffic, multi‑purpose spaces.

Constructed with a durable polycarbonate housing and designed to fit standard decorator wallplates, the OS306U‑W‑K offers a clean aesthetic and rugged performance, ensuring long‑term reliability in homes, offices, hallways, utility rooms, and more.
