CUI Devices


CUI Devices' AMT series is a range of rugged, accurate modular encoders which is available in incremental, absolute, and commutation versions. The AMT encoders measure rotary position in applications such as motor-control systems in industrial, automation, robotics and renewable-energy equipment.

Based on CUI Devices' proprietary capacitive sensing technology, the AMT products are immune to contaminants such as dirt, dust, and oil that commonly impair the performance of optical and other types of encoders in industrial environments. Because the AMT products are complete encoder systems with a locking hub, they are simple to assemble into end products.

The AMT10 and AMT11 series are incremental encoders available in up to 22 programmable resolutions and up to 4,096 positions per revolution.

Outputting 12 bits or 14 bits of absolute position information via an SSI, SPI or RS-485 communications interface, CUI Devices' AMT20, AMT21, AMT22 and AMT23 absolute encoders feature low current draw, compact packages, and simple assembly. Offered with single- and multi-turn options, the encoders are available in up to nine different sleeve bore diameters.

The AMT31 series commutation encoders generate standard U/V/W communication signals for commutating brushless DC motors.

The AMT31’s design simplifies the assembly process, reducing the time-consuming tasks of mounting and alignment to mere seconds with the One Touch Zero™ feature.
