Occupancy sensor switch · 600W 120V single-pole/3-way no neutral required black · Eaton OS306U-BK

What this product is for

This wall-mount occupancy sensor switch automatically controls lighting in rooms where lights are often left on, such as washrooms, storage rooms, utility spaces, offices and small commercial rooms. It is designed for 120V applications and can be wired as a single-pole or 3-way device.

Use for

Use for automatic lighting control of compatible 120V loads including incandescent, halogen, MLV, ELV, fluorescent, CFL and LED. The passive infrared sensor provides up to 450 sq ft (approximately 41.8 sq m) coverage with a 180 deg field of view, making it a practical choice for typical room entry and wall-switch locations.

Avoid for

Avoid using this device on circuits or loads outside the published ratings, or where a different control type is required such as dimming, 277V control or specialty automation systems. Confirm LED and ballast compatibility before installation.

Best for

Best for retrofit switch boxes where no neutral is available and where electricians need occupancy-based switching without adding extra control wiring. Commonly used in residential rooms and light commercial spaces that benefit from automatic ON/OFF lighting control.

Installed in

Installed in standard wall boxes in homes, condos, offices, back rooms, corridors and similar indoor spaces. Black finish suits black decorator device layouts.

Why this product exists

This sensor switch helps reduce wasted lighting energy by turning lights on when occupancy is detected and off after the selected delay. As typical guidance, occupancy sensors are commonly used where lights are frequently left on; actual savings depend on room use, sensor placement and load type.

Compared with similar products

Compared with a standard wall switch, this device adds automatic occupancy sensing and adjustable time delay. Compared with sensors that require a neutral, this model is useful for retrofit applications where only line and load conductors are present in the wall box.
