Overview
The RS91/RS90 series is a high-performance, optical three-channel incremental encoder module. It integrates a precision optical grating phase matrix reception chip and light source internally. With the code disk, the module can sense rotational position and speed information.
The RS91 series features an optical center of 11mm. The standard CPR values include: 50, 60, 100, 200, 256, 360, 400, 500, 512, 1000, 1024, 2000, 2048, and 2500.
The RS91 series also offers linear sensing products with standard LPI values of: 20, 45, 90, 150, 180, 300, and 360.
