- **Caution**: 

### Q: What is the difference between an encoder and a resolver in feedback systems?
**A**: Encoders use optical or magnetic code disks to provide digital position feedback with high resolution, while resolvers use electromagnetic induction with copper windings to deliver analog signals that are more robust in harsh environments with extreme temperatures or contaminants.

### Q: What industries commonly use feedback encoders/resolvers?
**A**: These devices are essential in machinery manufacturing, CNC machining, robotics, aerospace, automotive production, packaging equipment, and any application requiring precise motion control, position feedback, or velocity monitoring in industrial automation systems.

### Q: How do I choose between an encoder and resolver for my application?
**A**: Choose encoders for applications requiring high resolution, digital output, and clean environments. Select resolvers for harsh conditions with extreme temperatures, vibration, dust, or moisture, as they have no optical components and provide reliable analog signals through electromagnetic induction.
