CUI's AMT22 series is a rugged, high accuracy absolute encoder outputting 12 bits or 14 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 AMT22’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 AMT22 provides a compelling solution for a range of industrial, automation, robotics, and renewable energy applications.

AMT22-V Kit

Designed with flexibility in mind, the AMT22 series is also available as a kit that includes 9 sleeve options ranging from 2 mm to 8 mm, two simple mounting tools, and one standard and one wide baseplate with multiple pre-drilled mounting hole patterns designed to mate with a broad range of motors.
