CUI Devices' AMT33 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 AMT33’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 AMT33 provides a compelling solution for a range of industrial, automation, robotics, and renewable energy applications.
