AMT20 Series

28 mm, 12 Bit, Single-Turn, Absolute, SPI Interface, Capacitive Modular Encoder

CUI Devices' AMT20 series is a rugged, high accuracy absolute encoder outputting 12 bits of absolute position information with Serial Peripheral Interface (SPI) communication. 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 AMT20’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 AMT20 provides a compelling solution for a range of industrial, automation, robotics, and renewable energy applications.
