R3xxxx series is a high performance, low cost,  three-channel incremental encoder chip. It integrates precision grating phase array internally. With a high collimated light source and code wheel, it can sense rotary information of the servo motor. If a good parallel light source is used, the chip can be easily installed with a large tolerance.

R3xxxx series is designed with optical center as 11.2mm, standard CPR for 50, 60, 100, 200, 256, 300, 360, 400, 500, 512, 600, 1000, 1024, 1200, 1250, and 2500. In this way, clients’ installation is simple and will be convenient for mass production.

The index (Z) signal of the device provides 1 pulse (1T) width, 0.5 pulse (0.5T) width, and 1/4 pulse (1/4T) width.

The A/B signal of device has two times interpolation function, which makes it easy to obtain 5000CPR, simplifying complex process and improving production efficiency.

In order to improve the generic type on the market and convenience of customer usage and simplify the supply chain, R3xxx series brings convenience to customers with a unified optical center.
