## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is the difference between incremental and absolute position encoders?
**A**: Incremental encoders measure relative position changes and require a reference point, while absolute encoders provide unique position values immediately upon power-up without needing homing.

### Q: What environmental protection ratings are available for industrial position encoders?
**A**: Our position encoders typically feature IP65 to IP67 ratings, providing dust-tight protection and resistance to water jets or temporary immersion, suitable for harsh manufacturing environments.

### Q: How do I select the right resolution for my positioning application?
**A**: Resolution selection depends on your required positioning accuracy. For precision machinery, we recommend encoders with resolutions from 1μm to 0.1μm for linear models, or up to 24-bit for rotary models, based on your tolerance requirements.
