Cross-brand Replacement Recommendation
| Brand | Model | Main Difference |
| Pepperl+Fuchs | RVI58N-011K1R61N-1024 | 10mm shaft diameter, custom flange adapter required |
| Hengstler | RI58-O/1024EK.42KB | IP65 protection grade, slightly lower load capacity |
| Kübler | 8.5823.3832.1024 | Cost-effective, suitable for general industrial environments |
- Selection Notes
- Confirm shaft diameter is Ø16mm; select corresponding model for other sizes.
- Output type must be HTL differential; TTL output cannot be used as replacement (insufficient transmission distance and anti-interference capability).
- For motor shaft application, must adopt insulated shaft model to avoid encoder burnout by shaft current.
- Original model discontinued; prioritize in-stock replacement models to avoid supply outage risks.
729798-01 1024 PPR 9 Accurate Model Interpretation
- Segment Meaning
729798-01: Leine & Linde original ordering part number
1024 PPR: Pulse resolution = 1024 pulses per revolution
9: Voltage code → Rated supply 10～30 VDC
- Core Attributes
Type: Heavy-duty Incremental Industrial Encoder
Output: A/B/Z HTL differential signal
Operating Voltage: 10～30 VDC
Application: Lifting, port machinery, metallurgy, motor main shaft, variable frequency drive
- Key Matching Requirements
- Must strictly match 1024 PPR; incorrect pulse will cause position offset and counting error.
- Only 10–30 VDC power supply allowed; 5V TTL encoder cannot be substituted.
- Differential output is mandatory; single-ended output leads to poor anti-interference and pulse loss.
