AMT31 Series

28 mm, 48 ~ 4096 PPR, Commutation, Capacitive Modular Encoder

CUI Devices' AMT31 Series is a rugged, high accuracy commutation encoder that generates standard U/V/W communication signals for commutating brushless dc motors. Thanks to its innovative capacitive platform, the series is not susceptible to contaminants such as dirt, dust, and oil that typically plague encoders in industrial environments. The AMT31’s design also simplifies the assembly process, reducing the time-consuming tasks of mounting and alignment to mere seconds with the One Touch Zero™ feature. Combined with an operating temperature range of -40°C to +125°C, high accuracy, a compact package, and low current draw, the AMT31 provides a compelling solution for a range of industrial, automation, robotics, and renewable energy applications.
