Renishaw RGH41G30F06A Optical Encoder Read Head

Renishaw RGH41G30F06A Optical Encoder Read Head is a non‑contact optical read head from Renishaw’s RGH41 family, designed to provide precise position feedback in linear and rotary encoder systems. It outputs a digital signal with a 2 µm resolution and operates from a 5 V DC supply, enabling straightforward integration with standard motion controllers and Renishaw scales. This read head pairs with Renishaw scales to form a high‑precision encoder system widely used in CNC machine tools, metrology equipment, and automated positioning applications where tight tolerances and repeatable motion are required. The RGH41 family offers Renishaw’s established optical sensing with robust signal integrity, helping maintain accurate measurements in demanding manufacturing environments. Applications include machine tool axes, precision positioning stages, and robotic applications where reliable, high‑resolution feedback directly influences control accuracy and process stability.
