Hengstler Absolute Rotary Encoder ACURO AC61

Hengstler Absolute Rotary Encoder ACURO AC61

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 configuraion from over two million possible rotary encoders.

HENGSTLER's ACURO absolute rotary encoders offer innovative engineering, easy operation and optimised 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 AC61

The AC61 series combines a series of absolute rotary encoders with optical scanning that have been specially designed for use in extreme ambient conditions. The size 58 mm encoders have a stainless steel housing and are particularly suited to oil and gas applications, marine fittings, the food industry, packaging industry and offshore applications. As single-turn and multi-turn versions, these encoders achieve a resolution of up to 29 bits (17 bits single-turn, 12 bits multi-turn). Connection options are parallel output, Profinet, Profibus, CANopen, CANlayer2, DeviceNet and Interbus.
