- **Caution**: 

### Q: What is the difference between a position encoder and a resolver?
**A**: Encoders typically provide digital output signals with high resolution for precise position feedback, while resolvers are analog devices that offer robust performance in harsh environments with excellent reliability and noise immunity.

### Q: What materials are used in your position encoders for durability?
**A**: Our position encoders feature aluminum alloy housings for lightweight strength, stainless steel components for corrosion resistance, and high-quality PCB assemblies with magnetic or optical sensing elements for accurate signal conversion.

### Q: How do I select the right position encoder for my machinery application?
**A**: Consider your required resolution, accuracy, environmental conditions (temperature, vibration, contaminants), output signal type (incremental/absolute, analog/digital), and mounting configuration. Our encoders support various shaft couplings and sensor head designs for diverse industrial applications.
