- **Caution**: 

### Q: What's the difference between optical and magnetic servo encoders?
**A**: Optical encoders use a light source and code disc for high resolution, while magnetic encoders use magnets and Hall-effect sensors for better durability in harsh environments.

### Q: How does this encoder improve machinery manufacturing accuracy?
**A**: It provides precise real-time feedback on servo motor position and speed, enabling tighter control loops that reduce positioning errors and improve product quality in automated equipment.

### Q: What maintenance does this servo encoder require?
**A**: Minimal maintenance due to sealed housing and quality bearings. Optical versions may need occasional cleaning of code discs; magnetic versions are virtually maintenance-free.
