The Lutron Maestro Dual Technology Motion Sensor Switch uses both ultrasonic waves and passive infrared (PIR) technology to ensure reliable automatic sensing for a single circuit. This sensor switch is single pole only and rated to control up to 6A of lighting or 4.4A (1/6HP) fan motors. The sensor has a 180-degree field of view (900 sq ft major motion & 400 sq ft minor motion coverage) and is covered with a tamper resistant lens. It can be used to meet many of the Title 20/24, ASHRAE 90.1, and IECC code requirements such as “automatic shutoff”. This sensor is built with Lutron’s Dual Sensing Technology (PIR and ultrasonic) to detect very fine motion, such as typing at a desk or reading, ensuring lights do not turn off inadvertently. Lutron Maestro Sensors have an adjustable timeout (1, 5, 15 or 30 minutes), to control how long the lights stay on after you leave the room. Lutron’s, patent pending, adaptive zero-cross switching algorithm extends and maximizes the relay’s life by switching at the point of minimum energy on the AC power curve. It’s also equipped with smart ambient light detection (ALD), allowing you to customize your sensor to detect daylight, so lights don't turn on when there is enough natural light in the room. Easy to read programming buttons are directly on the sensor switch. Available in 10+ colors. Pairs perfectly with Lutron Claro wall plates for consistent color matching (sold separately).
