· Angle encoders usually refer to encoders with an accuracy of<8 "and a line count of up to 5000. Angle encoders are used for high-precision angle measurements that require accuracy within seconds.

· The main application range of closed angle encoder: CNC turntable; CNC milling head; Lathe C-axis; Gear measuring machine; High precision industrial robot joints; Astronomical telescopes, etc.

· Senyd's self-developed closed angle encoder series products mainly include built-in bearings, hollow shafts, and built-in couplings.

· The main characteristics of this series of products are: high measurement system accuracy, reaching the international advanced level of similar products. The built-in bearings and couplings eliminate the impact of machine tool components and torque generated by rotational acceleration on measurement accuracy.

· The installation is simple, and the built-in coupling expands the application range of axial installation to ± 0.5mm, reducing the difficulty of processing and assembling related accessories;

· The product adopts the principle of photoelectric scanning for measurement. Its Geodetic datum is glass grating.

· The use of self-developed lithography technology to produce precision gratings with uniform thickness and clear edges is the key to outputting high-quality incremental or absolute position signals.

· Senyd's closed angle encoder series products use two types of measurement methods: incremental and absolute.

· The specifications of incremental equidistant graduated circular gratings include: 36000 lines/circle, 18000 lines/circle, and 9000 lines/circle; The specifications of absolute equidistant graduated circular gratings include 16384 lines/circle, 32768 lines/circle, and 65536 lines/circle.

· The incremental grating also includes a reference code track with a single or multiple reference points (36 or 72 reference points) per turn. The measurement is based on the number of incremental signals relative to the reference point to determine the absolute position.
