Dual Tech Occupancy Sensor, 24VDC, Center Mount, 360°, 40Khz - Dual Technology Occupancy Sensor

The WattStopper DT-300 Series Dual Technology Ceiling Sensors combine passive infrared (PIR) and ultrasonic technologies to detect occupancy with high reliability. Designed for ceiling mounting, these sensors provide 360° coverage and are ideal for applications requiring precise occupancy detection to control lighting and HVAC systems. Suitable for electrical distributors and switchgear suppliers, they integrate easily with low-voltage power packs and support manual-on operation via low-voltage switches.
