Package Contents & Technical Specifications
Standard Configuration:
Linear Glass Scale: Model KA600, standard measuring length of 2100mm.
Reading Head: High-precision optical sensor unit.
Accessories: Mounting hardware and connection cables.
Performance Parameters:
Resolution: Available in precision grades of 0.5μm, 1μm, and 5μm to accommodate diverse application requirements.
Customization: We offer tailored encoder lengths (L0) ranging from 1000mm to 3000mm, ensuring a precise fit for specific machine bed dimensions.
Optical System & Encoding Principle:
Optical Sensing Mechanism: The encoder integrates a high-resolution optical scanning system. As the reading head traverses the scale, it detects the optical graduation patterns and converts them into precise electrical signals for position feedback.
Advanced Code Patterns: The scale utilizes sophisticated optical encoding techniques. We primarily implement Gray Code logic, as opposed to natural binary codes.
Error Minimization: The utilization of Gray Code ensures that only a single bit changes state between consecutive values. This fundamental design characteristic effectively mitigates data interpretation errors during rapid positioning transitions, thereby enhancing overall system stability.

Resolution & Mechanical Design
Resolution & Precision
The resolution of an absolute optical encoder is fundamentally determined by the density of the graduation patterns on the scale. Higher resolution is achieved through finer pitch markings, which directly translates to superior positioning accuracy. Resolution is typically quantified in Bits or Counts Per Revolution (CPR).
Mechanical Engineering for Large-Scale Applications
The NC600 encoder is specifically engineered for application in large-format CNC machine tools. It features a robust mechanical structure characterized by:
Superior Rigidity: The design emphasizes structural integrity to maintain stability under heavy loads.
Flexible Support Configuration: Additional mechanical supports can be integrated at any position along the encoder axis. This feature significantly enhances system rigidity and stability during operation.
Extended Measuring Range: Available in lengths ranging from 1000mm to 3000mm, catering to the requirements of large machine beds.
