Pass & Seymour DT305 Wattstopper Dual Technology Ceiling Occupancy Sensor, 24V 360°

Pass & Seymour DT305 Wattstopper Dual Technology Ceiling Occupancy Sensor, 24V 360°

The Pass & Seymour DT305 Wattstopper Dual Technology Low Profile Ceiling Mount Occupancy Sensor combines passive infrared and ultrasonic detection to deliver reliable 360° coverage for automatic lighting control. Operating at 24V with 40 kHz ultrasonic sensing, this ceiling-mount sensor uses patented ultrasonic diffusion technology to spread coverage across a wider area, making it well suited for commercial spaces, open offices, and common areas where dependable occupancy detection and energy savings are priorities. Quick-connect plug terminal wiring and configurable occupancy logic make it straightforward to specify and install in both new construction and retrofit projects.

Key Features

• Dual Technology Detection: Combines passive infrared and 40 kHz ultrasonic sensing for accurate, reliable occupancy detection.
• 360° Coverage: Low profile ceiling mount design provides a full 360° detection pattern for complete room coverage.
• 24V Operation: Engineered to operate on 24V for compatibility with standard low-voltage lighting control systems.
• Ultrasonic Diffusion Technology: Patented ultrasonic diffusion spreads coverage to a wider area than standard ultrasonic-only sensors.
• Plug Terminal Wiring: Uses a plug terminal wiring system for quick and easy installation and servicing.
