AN Ø70mm absolute encoder
The AN Ø70 mm Absolute Encoder is a high-resolution, single-turn optical encoder designed for precision motion control. It features a 22-bit BiSS-C interface for accurate digital output. The encoder uses optical reflectance sensors arranged at 180°, which eliminates mechanical errors such as shaft runout through advanced electronic compensation.
This encoder ensures reliable performance in demanding industrial and automation applications, even under vibration and shock conditions.
