As a high-precision position detection device, the multi-turn solid encoder can simultaneously record single-turn angular position and multi-turn rotation information, thus achieving more comprehensive position signal feedback.

Bearing-ess magnetic encoders (hollow shafts), as high-precision position sensors, are widely used in various industrial automation, robotics, and precision measurement fields.

From a hardware perspective, the subdivision technology of incremental linear encoders primarily relies on improvements in the precision of code disk manufacturing.

In modern industrial automation systems, the incremental optical encoder, as a core sensor for position and velocity feedback, directly impacts the control accuracy and operational safety of the equipment.

The manufacturing precision of the grating ruler directly determines the resolution. High-precision encoders require the use of a laser interferometer to calibrate the grating spacing to ensure that the error is less than the micrometer level.

Traditional incremental encoders cannot provide absolute position information, while early multi-turn absolute encoders relied on mechanical gear sets to record the number of turns, resulting in defects such as wear, short lifespan, and poor shock resista
