Optical System & Encoding Principle
The encoder adopts a high-resolution optical scanning system. As the reading head moves along the scale, it detects the graduation patterns and converts them into accurate position feedback signals.
The scale uses advanced optical encoding, mainly Gray code. Compared with natural binary code, Gray code allows only one bit to change between adjacent positions, which effectively reduces signal reading errors during high-speed movement and improves system stability.

Resolution & Mechanical Design
Resolution & Precision
The resolution of an absolute optical encoder depends on the density of the graduation markings on the scale. Finer graduations provide higher resolution and improved positioning accuracy. Resolution is usually expressed in bits or Counts Per Revolution (CPR).
Mechanical Engineering for Large-Scale Applications
The NC600 encoder is specially designed for large CNC machine tools, with a rugged mechanical structure offering:

• Superior Rigidity: The design emphasizes structural integrity to maintain stability under heavy loads.
• High Rigidity: Stable structural design ensures reliable performance under heavy loads.
• Flexible Support: Additional supports can be installed at any point along the encoder to increase rigidity and operational stability.
• Extended Measuring Range: Measuring lengths from 1000 mm to 3000 mm, ideal for large machine beds.
