New Incremental Encoder Supports Smaller Shaft Sizes from 1 to 6.35 mm

New Incremental Encoder Supports Smaller Shaft Sizes from 1 to 6.35 mm

CUI Devices’ Motion and Control Group today announced the introduction of a new model to its AMT incremental encoder family that supports smaller motor shaft sizes from 1 mm to 6.35 mm (1/4 inch). The AMT12 series, based on CUI Devices’ proprietary capacitive ASIC technology, brings the same high levels of durability, accuracy, and immunity to environmental particulates as current AMT encoder models in an even more compact 22.2 x 22.2 x 12.8 mm package. Thanks to its 16 programmable resolutions from 96 to 4096 PPR and low current consumption of 16 mA at 5 V, the AMT12 incremental encoder is ideally suited for a variety of robotics, industrial, and automation applications.

Available in radial or axial orientations, the AMT12 series carries a wide -40 to +125°C operating temperature range and single-ended quadrature A/B output channels. Its digital nature and compatibility with CUI Devices’ AMT Viewpoint™ software makes the AMT12 encoder highly customizable with the ability to easily configure the resolution and set the zero position.


  • Product name: AMT12 Series, AMT12-V Kit
  • Availability: Stock to 8 weeks
  • Possible users: Robotics, industrial, automation applications
  • Primary features: Supports shaft sizes from 1 to 6.35 mm, compact 22 mm package
  • Cost: $21.66 per unit at 100 pieces through distribution

The AMT12-V kit affords users further flexibility in their design with the support of 8 different sleeve bore sizes from 1 mm to 6 mm and simple mounting tools to assist in the easy installation process onto a motor.

The AMT12 series is available immediately with prices starting at $21.66 per unit at 100 pieces through distribution. Please contact CUI Devices for OEM pricing.
