The NexLight family of wall switch occupancy/vacancy sensors provides a simple yet cost-effective lighting control solution for many retrofit applications. Designed with contractors in mind, the NexLight 0-10V dimming wall switch sensor is significantly shallower than typical dimmers and sensors, resulting in less crowed wall boxes. Additionally, versatile wiring enables usage with or without a neutral and allows reversal of line and load connections. 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. For dimming adjustment, intuitive raise and lower buttons are present in addition to an on/off button.
