The Definition and Advantages of Absolute Rotary Encoder

An absolute rotary encoder is a high-precision motion sensing device that converts mechanical rotational motion into unique digital code signals, which can record the absolute angle position of the rotating shaft even after power failure. Compared with incremental rotary encoders, absolute rotary encoders have the advantages of high precision, no position loss, and strong anti-interference ability, making them widely used in high-end industrial scenarios that require accurate absolute position detection, such as CNC machine tools, robotic arms, precision measuring equipment, and aerospace equipment.

Sensyor Electric specializes in the R&D and production of high-quality absolute rotary encoders. Sensyor Electric absolute rotary encoder strictly follows the ISO9001:2015 quality management system and has obtained CE international certification. Our product series covers various specifications of absolute rotary encoders, including 38mm, 40mm, 45mm, 48mm, and 50mm outer diameter models, with pulse resolution ranging from 1000PPR to 10000PPR, meeting the needs of different high-precision application scenarios.

Our absolute rotary encoders have obvious advantages in performance. Sensyor Electric absolute rotary encoder adopts high-precision code discs and advanced sensing technology, ensuring positioning precision up to ±0.1° and stable signal output. The shell is made of high-strength aluminum alloy, with a sealed structure that achieves IP65 protection grade, effectively preventing dust and moisture from entering. With strict quality control and comprehensive performance testing, our absolute rotary encoders can operate stably for a long time, becoming the first choice for high-precision motion control scenarios.
