SensorWorx SWX-421-B Wireless Dual-Tech Occupancy Sensor, 120° Wide View, Battery Powered

Product Overview

The SensorWorx SWX-421-B is a wireless, battery-powered dual-technology occupancy sensor designed for commercial lighting control systems. It combines passive infrared (PIR) and acoustic detection to sense occupancy and wirelessly signal connected load controllers to manage lighting based on room activity.

Key Features & Design

• Functionality: Detects occupancy using dual-technology sensing (PIR + acoustic) and wirelessly signals connected load controllers to control lighting based on room activity.
• Installation context: Wireless, battery-powered sensor designed for flexible placement without hard-wired connections.
• Notable specifications: Dual-technology sensing (PIR + acoustic); 120° wide-view coverage; battery-powered operation using a CR123(A) lithium battery; wireless communication with compatible controllers.
• Contractor-relevant details: Wireless design simplifies installation and pairing with compatible load controllers, reducing wiring and supporting scalable lighting control across commercial spaces.

Performance / Benefits

In real-world use, the SWX-421-B delivers reliable occupancy detection by combining PIR motion sensing with acoustic detection to improve accuracy in spaces with obstructions or limited movement. Its wide-view coverage and wireless design enable flexible placement and efficient lighting control, helping reduce energy consumption while maintaining consistent illumination in commercial environments.
