Hengstler Absolute Rotary Encoder ACURO AC58

Absolute Rotary Encoder ACURO AC58

Technology and flexibility are key characteristics of our incremental and absolute rotary encoder series ICURO and ACURO. Monolithically integrated Opto-ASICS will reliably replace up to 200 SMD components. Thanks to the modular construction, users can select the required configuration from over two million possible rotary encoders.

HENGSTLER's ACURO absolute rotary encoders offer innovative engineering, easy operation, and optimized functional dependability. The platform-based concept enables particularly compact construction and modular internal components. As a result of this sophisticated modular system, HENGSTLER is in a position always to provide the right variant for applications involving motor feedback and automation. Equipped with an open BiSS sensor interface, these rotary encoders are ideal for all requirements and prepared for the future.

Absolute Rotary Encoder ACURO AC58

The AC58 series combines a series of absolute rotary encoders with optical scanning for numerous fields of application. The 58 mm encoders are available as solid-shaft or hollow-shaft models and meet the requirements for nearly every demanding industrial application and use involving motor feedback. As single-turn and multi-turn versions, these encoders achieve a resolution of up to 34 bits (22 bits single-turn, 12 bits multi-turn, depending upon interface). Apart from connections by SSI/ BiSS, many other interfaces such as EtherCAT, Profinet, Profibus, CANopen, CANlayer2, DeviceNet, Interbus, and SUCOnet are available.
