The CMRB-10 Series occupancy sensor mounts directly to the end of a pendant or surface mount fixture and utilizes the industrys leading Passive Infrared (PIR) technology to provide maximum viewing from the ceiling. The sensor is line powered and can switch loads directly without the need for a Power Pack. When mounted at 9 feet, this sensor views up to 28 feet in all directions. Its circular coverage pattern is designed for walking motions; making it ideal for T-shaped intersections in corridors, or other areas where wall mounting a sensor is not practical. The CMRB-10 is also the best sensor for low ceiling applications. For example, when mounted at only 7 feet, the height of pick aisles in many distribution centers, the CMRB-10 provides a 32 foot diameter pattern of coverage. In applications where detection of minor motion is also required, use the CMRB-PDT-10 Series Dual Technology sensor. For freezer or high humidity applications, use the LT version.
