White rectangular fixture mount sensor with lens and wiring terminals

Acuity Sensor Switch

Acuity Sensor Switch CMRB 6 LT Fixture Mount Sensor Occupancy Photocell 0 to 10V

SKU CH-PWGY-8JGBF

Fixture-mount occupancy sensor with passive infrared detection, photocell, and 0–10 V dimming for fluorescent, incandescent or LED loads up to 800 W at 120 V, covering 2 827 sq ft at heights to 45 ft

  • Fixture-mount sensor enables easy installation
  • PIR occupancy detection up to 2,827 sq ft at 45 ft mounting height
  • Built-in photocell supports daylight harvesting for energy savings
  • 0-10V dimming compatible with fluorescent, LED and incandescent loads
  • cUL listed and RoHS compliant for safety and environmental standards

High-Bay Occupancy Sensor

The SENSORSWITCH CMRB 6 LT mounts directly to a fixture and uses passive infrared technology to detect occupancy in high-bay environments. It operates on 120, 230, or 277 volts AC and covers up to 827 square feet at mounting heights up to 45 feet.

Photocell and 0-10V Dimming

An integrated photocell holds lights off when sufficient daylight is present, reducing energy use. The 0 to 10 volt output provides continuous dimming control for compatible fluorescent, incandescent, or LED loads up to 800 watts at 120 volts.

Fixture-Mount Construction

Hard-wired communication and a fixture-mount design suit permanent industrial or commercial installations. The white housing carries cUL listing and RoHS compliance, and the unit supports a maximum load of 6.67 amps at 120 volts AC.

Questions about this item

Does the PIR lens or photocell need periodic cleaning to keep the occupancy detection accurate?

The fixture-mount sensor uses a passive infrared lens that should be kept free of dust and debris; a soft dry cloth is sufficient for routine cleaning.

At the 45 ft mounting height the 2 827 sq ft coverage pattern is the first limit reached before the 800 W load rating?

Yes, the 2 827 sq ft detection zone at 45 ft is the primary constraint; the 800 W at 120 V rating provides ample headroom for typical high-bay LED loads.

How much heat does the unit add to the fixture when it powers an 800 W load continuously?

The sensor itself draws minimal power and adds negligible heat; the 800 W rating reflects the connected lighting load, not internal dissipation.
