Wattstopper® Passive Infrared DIMMR Wall Switch U-Sensor, 120/277V, Gray - Occupancy Sensor

The Wattstopper® PW-101D passive infrared (PIR) dimmable wall switch occupancy sensor is designed for automated lighting control in small, enclosed spaces such as offices and conference rooms. It detects occupancy using advanced PIR technology to switch lighting ON and OFF, providing energy savings and convenience for electrical distributors and lighting solutions providers. The device replaces existing wall switches, fits a single gang junction box, and requires a neutral connection. It supports dimming control from 10% to full output and is compatible with various lighting types including incandescent, MLV, ELV, and two-wire fluorescent ballasts.
