Absolute Rotary Encoders

Micromech supplies high-performance absolute rotary encoders from Same Sky designed for accurate position feedback in industrial motion control systems. Available in single-turn and multi-turn configurations, these capacitive encoders provide reliable, high-resolution feedback for robotics, automation machinery, servo systems, and precision motion applications.

Same Sky’s AMT20, AMT21, AMT22, AMT23, AMT24 and AMT25 Series are high-accuracy capacitive absolute rotary encoders designed to provide reliable position feedback for demanding industrial motion control applications.

Using Same Sky’s capacitive sensing technology, the AMT20–AMT25 Series provides precise angular position feedback while offering resistance to contaminants such as dust, dirt and oil. This makes the range well suited to industrial environments where reliable and consistent encoder performance is required.

The range includes single-turn and multi-turn absolute encoder options, with SPI, SSI and RS-485 communication interfaces available depending on the series. Absolute position feedback enables the system to retain position information without requiring a homing sequence each time the equipment is powered on.

Compact modular construction and multiple bore options simplify integration into motors and machinery, while features including One Touch Zero™ and configuration using AMT Viewpoint™ help streamline encoder setup and commissioning.

The AMT20–AMT25 Series is suitable for applications including servo motor feedback, robotics, automated machinery, material handling equipment and other precision positioning and industrial automation systems.

Micromech supplies Same Sky absolute rotary encoders as part of its range of motion control and position feedback solutions for UK machine builders and automation applications.
