GSI6 Magnetic Linear Encoder with Precision Guiding Unit
The GSI6 is a guided magnetic linear encoder designed for high‑precision positioning tasks. The precision guiding unit with a play‑free carriage ensures absolutely straight, stable and low‑vibration movement. This makes the magnetic measuring system ideal for applications requiring maximum repeatability and mechanical rigidity.
As a robust and low‑maintenance alternative to glass scales, the system has been specifically developed for use in bending machines and other demanding mechanical engineering applications.
