New Product Highlights


The Intermatic® line of occupancy sensors are engineered and tested for long-lasting performance. In-Wall and Ceiling Mount sensors in both PIR (infrared) and dual (PIR/ultrasonic) technologies can monitor virtually any area within a building, providing solutions for any retrofit or new construction project. They utilize zero-crossing technology to suppress inrush current impact, supplying reliable ON/OFF sensing no matter the lighting technology.


The Intermatic® ICUBE™ Adaptive Defrost Module cuts defrost cycles--and utility bills--for the food service industry. Designed by Grässlin by Intermatic for commercial walk-in coolers and freezers, the smart-sensing technology behind the ICUBE™ continuously monitors evaporator coil temperatures and only allows defrosting when necessary at the next programmed timer interval.
