AI Overview
High-resolution and high-precision optical glass code discs are
critical components for rotary encoders, offering superior accuracy, thermal stability, and, in some cases, up to 1,270 lines per inch (lpi) or 5,000+ pulses per revolution (PPR). Made from soda-lime or borosilicate glass, these disks are etched with low-reflective chrome (LRC) to provide precise, high-contrast feedback for speed and position control in robotics, motors, and measuring equipment.Key Characteristics and Applications
Common Specifications
- Material: Soda-lime glass, Borosilicate, Quartz.
- Pattern Material: Low Reflective Chrome (LRC).
- Optical Density: 2.8 to 5.0+.
- Operating Temperature: Up to +120°C.
These components are crucial when high accuracy is required over long operating cycles in demanding industrial environments.
