AMM33 bearingless kit encoder, a bearingless kit encoder for motion control.

AMM33 absolute multiturn kit encoder

The energy harvesting absolute multiturn kit encoder delivers maintenance-free position feedback for robotics, servo motors, drones, and medical devices. Unlike conventional multiturn encoders, it uses energy harvesting technology to maintain the multiturn count without a battery, reducing maintenance while increasing long-term reliability.

Built with robust magnetic sensing technology, the encoder provides single-turn resolution up to 18 bits and multiturn resolution up to 24 bits. As a result, it delivers accurate absolute position feedback immediately after power-up, eliminating the need for homing and ensuring reliable operation over multiple revolutions.

The encoder supports BiSS-C and SSI communication interfaces, allowing fast, dependable integration with servo drives, PLCs, and industrial motion controllers. Its modular, bearing-free design also makes it easy to install inside compact motors and robotic actuators.

Designed for demanding environments, the encoder operates at temperatures up to 115°C and supports shaft speeds of up to 12,000 rpm. Consequently, it is an excellent choice for high-performance motion control applications that require durability, compact size, and maintenance-free operation.
