Description
The SINO Digital Readout Systems SDS2MS and SDS3MS are advanced digital readout (DRO) units engineered to deliver precise and reliable position measurement for machine tools. Designed for milling machines, lathes, grinders, and other precision equipment, these DRO systems convert encoder or scale signals into clear digital readouts, improving machining accuracy and efficiency.
The SDS2MS model provides accurate two-axis (X & Y) measurement, while the SDS3MS extends capability to three axes (X, Y & Z), making it suitable for more complex machining tasks. With a bright, easy-to-read LED/LCD display and intuitive keypad controls, operators can quickly set zero positions, enter preset values, switch between absolute and incremental modes, and recall saved positions. The systems are compatible with a wide range of linear glass scales and magnetic encoder strips, allowing flexible installation on both manual and retrofit machines.
