Low Voltage Ultrasonic Fixture Integrated Occupancy Sensor Lighting Control

The Low Voltage Ultrasonic Fixture Integrated Occupancy Sensor by WattStopper utilizes 40 kHz ultrasonic technology to detect occupancy and control lighting automatically. Designed for integration into low-profile lighting fixtures, this sensor is ideal for applications including offices, conference rooms, restrooms, hallways, and stairwells. It operates at 24 VDC and connects via a modular plug-in system with an RJ45 connector and a 3-foot cord, providing flexibility and ease of installation. The sensor is typically paired with the FS-PP Power Pack to manage lighting loads effectively, making it a suitable solution for electrical distributors and lighting solutions providers focusing on energy-efficient wire and cable and switchgear supplier markets.
