Output Type Selection Guide
| Application Requirement | Recommended Selection | Reason |
|---|---|---|
| Highest Resolution | AV (Analog) + Interpolator | Can achieve 0.1um or higher |
| System Simplification | DR1 / DR05 (Digital) | Direct connection to controller, no interpolator needed |
| Long Distance Transmission | DR (RS422) | Differential signal for noise immunity |
| High Speed Motion | AV or DR5 | Lower resolution suitable for high speed |
| Cost Consideration | DR2 / DR5 | No additional interpolator required |

Ordering Notes
Important Reminders
- Size 15 only available in ND/CD fully hardened rail types
- AMS 4B carriages have integrated read heads, output interface type must be specified
- Analog output (AV) requires separate interpolator and cable purchase
- Digital output (DR) requires separate digital cable purchase
- Incremental systems require homing procedure after power-on
- For absolute measurement, select AMSABS 4B series
