EC-DIR-WH Wired Daylight Sensor With Infrared Receiver, White

Product Description

EC-DIR-WH Wired Daylight Sensor With Infrared Receiver, White by Lutron is a high-performance sensor designed for precision daylight harvesting applications. Engineered for seamless integration with Lutron ballasts and control modules, this sensor automates light adjustments based on ambient daylight, ensuring energy efficiency and occupant comfort.

• Enhances energy savings by automatically dimming lights based on available daylight levels.
• Enables personal control and advanced system programming through integrated infrared receiver.
• Designed for easy ceiling or fixture installation with adjustable mounting stud.
• Ensures system safety and reliability with flame-retardant construction and electrostatic discharge resistance.

• Daylight harvesting sensor designed for Lutron systems to maintain consistent light levels.
• Receives IR programming signals up to 8.2 ft (2.5 m) away for remote adjustments.
• Mounts on ceiling tiles or fixtures using a threaded stud, which can be shortened for tight spaces.
• Calibrated daylight sensitivity via the connected lighting control system for precise light regulation.
• Constructed from flame-retardant materials, compliant with IEC 801-2 standards for durability and safety.
