The NexLight family of wall switch occupancy/vacancy sensors provides a simple and cost effective lighting control solution for many applications. Just like its line voltage counterpart, the low voltage NexLight wall switch sensor is designed with contractors in mind. Less than 1" deep, the unit is 25-40% shallower than typical dimmers and sensors, resulting in less crowded wall boxes. NexLight products utilize the latest passive infrared technology and digital signal processing techniques to provide unmatched motion detection performance. These units are also available with an integrated microphone to provide overlapping passive acoustic occupancy detection for rooms with obstructions or where occupant motion is limited.
