Ultrasonic Ceiling Occupancy Sensor, 24VDC, 2000 sq ft

Ultrasonic Ceiling Occupancy Sensor, 24VDC, 2000 sq ft – Ultrasonic Occupancy Sensor The WattStopper UT-300-3 Ultrasonic Ceiling Occupancy Sensor is designed to automatically control lighting based on occupancy detection. This sensor operates on 24 VDC/VAC and uses 40 kHz ultrasonic frequency to detect motion, providing reliable lighting control for commercial and office environments. Its ceiling-mount design offers a low-profile, unobtrusive appearance with 360° coverage, making it suitable for applications such as restrooms, large offices, open office areas, and hallways. The sensor supports integration with building automation systems (BAS) or HVAC through an isolated relay and is compatible with low-voltage momentary switches for manual control.
