- **Caution**: 

### Q: What types of sensors are used in the Feedback Encoder and how do they affect performance?
**A**: The Feedback Encoder utilizes either photoelectric sensors with glass/metal code discs for high-resolution optical sensing or magnetic sensors for rugged environments. Photoelectric sensors offer superior precision for precise positioning applications, while magnetic sensors provide better durability in harsh conditions with dust, moisture, or vibration.

### Q: How does the aluminum alloy housing and stainless steel shaft contribute to encoder reliability in industrial machinery?
**A**: The aluminum alloy housing provides excellent corrosion resistance and heat dissipation while maintaining lightweight durability. The stainless steel shaft ensures superior mechanical strength, wear resistance, and protection against shaft deflection, making the encoder suitable for high-load industrial applications with extended service life.

### Q: What signal output options are available and how do they integrate with different servo control systems?
**A**: The Feedback Encoder provides standard digital outputs including incremental quadrature signals (A/B/Z) for position and direction feedback, along with optional analog sine/cosine outputs for high-resolution applications. These outputs are compatible with most PLCs, motion controllers, and servo drives, with signal processing circuits ensuring noise immunity and reliable communication in industrial environments.
