UW-200-LA, Wall Switch Occupancy Sensor

UW-200-LA, Wall Switch Occupancy Sensor – Ultrasonic Dual Relay Lighting Control The UW-200-LA Wall Switch Occupancy Sensor by WattStopper is an ultrasonic dual relay sensor designed for precise occupancy detection and energy-efficient lighting control. Ideal for electrical distributors and lighting solutions providers, this sensor fits into a single gang junction box and controls two independent lighting loads or circuits. It uses high-frequency ultrasonic technology to detect occupancy, automatically turning lights on or off based on room usage. The sensor includes a built-in light level sensor for bi-level control, optimizing daylight harvesting to reduce energy consumption. Suitable for applications such as individual restrooms, utility rooms, and spaces with partially obstructed occupant views, it supports energy code compliance and offers flexible control options for commercial and institutional lighting systems.
