FS-505C Fixture Integrated Occupancy Sensor for Lighting Solutions

The FS-505C is a low voltage ultrasonic fixture integrated occupancy sensor designed for open area lighting control. Manufactured by WattStopper, this sensor utilizes 40 kHz ultrasonic technology to detect occupancy through sound wave reflection, enabling automatic lighting control even without direct line of sight. Ideal for integration into lighting fixtures, it is suitable for applications such as open office spaces, conference rooms, restrooms, hallways, and stairwells. The sensor operates with a 24 VDC power supply and requires connection to an FS-PP power pack for operation, making it a reliable component for electrical distributors and switchgear suppliers focusing on energy-efficient lighting solutions.
