SensorWorx SWX-221 Ceiling PIR Occupancy Sensor, 360°, 12–24V Low Voltage

Product Overview

The SensorWorx SWX-221 is a ceiling-mounted PIR occupancy sensor designed for low-voltage lighting control systems. Operating on 12–24V AC/DC, it provides provides 360-degree PIR motion detection and signals a connected power pack to control lighting based on occupancy in commercial environments.

Key Features & Design

• Functionality: Detects occupancy via 360-degree PIR motion sensing and signals a connected power pack to control lighting based on presence.
• Installation context: Ceiling-mounted design suited for open offices, hallways, and other commercial environments where overhead sensing is appropriate.
• Notable specifications: This sensor uses passive infrared (PIR) motion detection with 360° coverage, operates on 12–24V AC/DC low-voltage systems, and signals a connected power pack for occupancy-based lighting control.
• Contractor-relevant details: A single ceiling-mounted sensor can simplify installation and provide broad coverage in typical office layouts, supporting energy-management goals in both new installations and renovations.

Performance / Benefits

In real-world use, the SWX-221 helps trim lighting energy consumption by ensuring lights operate only when spaces are occupied. Its 360‑degree coverage is well-suited for open-plan offices, reception areas, and conference rooms, delivering occupancy-driven lighting control that aligns with everyday workflow and space usage.
