Overview
The RK_L / S Series is a high-performance, cost-effective optical incremental encoder module that operates over a wide voltage range. It integrates a precision grating phase matrix receiver chip and light source. When paired with a code disk, this module can detect rotational position and speed information. It is designed for applications requiring precise position and speed measurement and comes in various LPI options to suit different needs.
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.
