Compact, Low Power Absolute Encoders Offer 12-bit or 14-bit Resolutions

4 APRIL 2018

CUI’s Motion Group ( https://www.cui.com/catalog/motion ) today announced the addition of two absolute encoder series, outputting 12 bits or 14 bits of single-turn absolute position information, to its line of AMT modular encoders. ( https://www.cui.com/amt-modular-encoders ) The AMT21 series, featuring high speed RS-485 communication, and the AMT23 series, designed with a Synchronous Serial Interface (SSI), are based on CUI’s proprietary capacitive sensing technology. The capacitive platform offers a highly durable and accurate position feedback solution that is resilient to the dirt, dust, and oil typically encountered in motion applications. Housed in compact packages measuring as small as 1.53 x 1.12 x 0.40 inches (39 x 28 x 10 mm) with a locking hub for easy installation, the two series boast a low current draw of 8 mA at 5 V and accuracy of ±0.2 mechanical degrees, making them ideally suited for battery-powered industrial, robotics, and automation applications.

Both models come in either radial or axial orientations and carry an operating temperature range from -40 to +105°C. Thanks to the digital nature of these absolute encoders, the AMT21 and AMT23 are highly customizable and configurable with the ability to program the direction of rotation and zero position via CUI’s AMT Viewpoint™ software. ( https://www.cui.com/amt-register ) The AMT’s simple design further reduces the time consuming tasks of mounting and alignment to mere seconds with the One Touch Zero™ feature.

Designed to mate with a broad range of motors, the AMT21 and AMT23 are also featured as a kit that contains 9 sleeve bore 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, offering users the ultimate flexibility in their design.

The AMT21 and AMT23 series are available immediately with prices starting at $45.17 per unit at 50 pieces through distribution. Please contact CUI for OEM pricing. ( https://www.cui.com/contact )
