New Incremental Encoder Supports Larger Shaft Sizes, Addresses Lead Time Constraints

LAKE OSWEGO, Ore. — January 31, 2023 — CUI Devices’ Motion and Control Group today announced the introduction of a new series to its AMT incremental encoder family. Based on the existing AMT13 series package, the new AMT13A series is not subject to silicon related lead time constraints and can serve as a drop-in replacement for AMT13 encoder models. AMT13A encoders offer 16 quadrature resolutions from 96 to 4096 PPR, selectable via an on-board DIP switch, while supporting larger motor shaft sizes from 9 mm to 15.875 mm (5/8 inch).

Thanks to CUI Devices’ proprietary capacitive ASIC technology, the AMT13A series delivers high levels of durability, accuracy, and immunity to environmental factors. It features compact radial and axial package types with a locking hub for ease of installation and low power consumption of 8 mA at 5 V. The AMT13A series also carries an operating temperature range from -40 to 125°C and offers differential line driver versions.

The AMT13A-V kit affords users further flexibility during development and design with the inclusion of 9 different sleeve bore options from 9 mm to 15.875 mm and three simple mounting tools. These all-in-one kit components combine to simplify the installation process onto a motor and greatly reduce SKU count in production.

The AMT13A series is available immediately with prices starting at $38.10 per unit at 100 pieces through distribution. Please contact CUI Devices for OEM pricing.
