Applies Lutron's exclusive XCT Technology (Dual Tech) to the ultrasonic as well as the passive infrared technology in this sensor to create a product that can detect very fine motion, such as typing. Includes all of the great features found in the rest of the Maestro sensor family, including: adaptive relay switching, smart ambient light detection, and simple button presses for changing settings. XCT technology for major, minor, fine, and very fine motion detection. 180 degree field-of-view. Tamper-resistant PIR lens. Up to 900 ft2 (81 m2) major motion coverage and 400 ft2 (36 m2) minor motion coverage. Two ambient light detect (ALD) options: Learning ALD mode: uses adaptive algorithm. Sensor learns user's preferred light level over time. Fixed ALD mode: four selectable light level thresholds: Hi, Med, Low, Min. Can be set to auto-on/auto-off or manual-on/auto-off per circuit. Adjustable timeout for each circuit (1, 5, 15, or 30 minutes). Sensitivity adjustment: PIR (Hi, Med, Min), ultrasonic (Hi, Med, Low, Off). Switches all lighting loads: incandescent, halogen, ELV, MLV, CFL, LED, magnetic fluorescent, electronic fluorescent. Switches fan loads at 120 V. Requires neutral wiring.


  • Includes (1) Lutron Maestro Dual Circuit Dual-Tech Motion 6A Sensor Switch; Satin Finish
  • Controls (2) individual circuits, each rated up to 6A lighting, 4.4A (1/6HP) fans motors, or 4.4A combined fan/light
  • Ground or Neutral required; 120-277V
  • Functions as either (2) single pole circuits or (1) single pole and (1) 3-way circuit with an existing 3-way switch
  • Lutron Dual Sensing Technology: Ultrasonic and PIR (Passive-Infrared) for major, minor, fine, and very fine motion detection
  • 180-degree sensor field of view (900 sq ft major motion & 400 sq ft minor motion coverage); tamper resistant lens
  • Smart Ambient Light Detection (ALD) can be programmed so lights stay off if enough light is present in the room
  • Complies with Title 20/24, ASHREA 90.1 and IECC requirements for “automatic shutoff” and “multi-level lighting control
  • Easy to read programming buttons directly on sensor; Settings include timeout, sensitivity, and programmable circuit swapping (eliminates rewiring after installation) and more
  • Available in 10+ colors; Pairs perfectly with Lutron Claro wall plates for consistent color matching (wall plates are sold separately)
