The Lutron Maestro Motion Sensor Switch features Lutrons advanced motion sensing technology to automatically turn the lights on and off, or manually toggle the lights with the tap switch. The Motion Sensor Switch is rated up to 5A for any lighting type, 3A fan or 3A for combined light/fan. Install in a single pole, 3-way with one existing switch, or with Maestro companion switches (MA-AS/MSC-AS) to switch from up to 9 locations. The passive infrared (PIR) sensor, covered by a tamper resistant lens, detects heat from occupants moving and has a 180-degree field of view (900 sq ft major motion & 400 sq ft minor motion coverage). Equipped with smart ambient light detection (ALD), you can customize your sensor to detect daylight, so lights don't turn on when enough natural light is present in the room. Unlike other manufacturers, Lutron sensors use Cross Correlation Technology (XCT) to also detect fine motion, such as typing at a desk or reading a book ensuring lights wont turn off inadvertently when youre still in the room. Lutron sensors also have an adjustable timeout (1, 5, 15 or 30 minutes) to control how long the lights stay on after leaving the room. Switch the sensor to vacancy mode to meet Title 24 requirements: lights only turn on with a manual press of the tap switch but automatically turn off if the sensor no longer detects motion. The sensitivity of the PIR sensor can also be changed so it only detects larger motion Available in 10+ colors. Pairs perfectly with Lutron Claro wall plates for consistent color matching (sold separately).
