PIR Motion Sensor, Daylight Harvesting, 12VDC, Indoor

The Trace-Lite LE-MS-ECO3 PIR Motion Sensor is a LiteLogic-compatible, low-voltage sensor designed to provide occupancy detection and daylight harvesting control for commercial lighting systems. Engineered for integration with the LE-C1 fixture controller, the sensor enables wireless Bluetooth mesh lighting control and automated energy savings in indoor environments. The unit features a built-in passive infrared (PIR) sensor that detects motion within a coverage area of up to approximately 16 feet, making it ideal for low-bay and general indoor applications. The sensor is designed for mounting heights up to 15 feet and includes a low-bay lens optimized for accurate occupancy detection. Operating on 12VDC input, the LE-MS-ECO3 connects directly to compatible LiteLogic controllers and provides output for lighting control functions including occupancy sensing and daylight harvesting. When paired with the LE-C1 controller, the system can be configured using a smartphone interface, allowing quick setup of lighting behavior such as automatic on/off, dimming, and daylight response. The sensor enables advanced control strategies including bi-level lighting, vacancy sensing, and daylight-responsive dimming, helping reduce energy consumption and extend fixture life. Its compact design allows easy integration into compatible luminaires or mounting locations within the lighting system. Constructed with UL 94-5VA rated housing and finished in white, the unit is designed for durability in commercial environments. It is UL listed and rated IP20 for indoor use, with an operating temperature range from -30 DegC to 55 DegC, ensuring reliable performance across a wide range of conditions. The LE-MS-ECO3 must be used in conjunction with the LE-C1 fixture controller and is compatible with a wide range of Trace-Lite luminaires, forming part of a scalable LiteLogic wireless lighting control system. Ideal for offices, classrooms, retail spaces, and light industrial environments, the Trace-Lite LE-MS-ECO3 PIR Motion Sensor provides an efficient and flexible solution for occupancy-based lighting control.
