| Voltage | 24-48 V | 12-48 V |
| Price (catalog, not a live quote) | 98.9 USD | 132.9 USD |
| Encoder (resolution is not accuracy) | Optional Hall-sensor version; bare frameless kit (add own encoder) | Optional Hall-sensor version; bare frameless kit (add own encoder) |
| Complete actuator efficiency | Unknown: not documented | Unknown: not documented |
| Cooling / thermal duty | Unknown: not documented | Unknown: not documented |
| Loaded repeatability | Unknown: not documented | Unknown: not documented |
| Calibrated simulation model | Unknown: not documented | Unknown: not documented |

Sensor bits do not establish loaded accuracy. CAD geometry is not a calibrated simulation model. Verify thermal conditions, duty and exact revision before engineering use.

Catalog photo; illustrative. Confirm hardware revision/variant.

Catalog headline specs spot-checked: confirm revision. The legacy verified flag is a catalog spot-check, not verification of every field, installed revision or independent performance validation. Catalog entry only; confirm the exact revision and operating conditions with the linked source.

## Arithmetic from catalog values

Differences are subtraction of retained catalog values, not measured advantages. Ratings may have different test conditions. Unknown means not documented; manufacturer claims and catalog spot-checks are not independent validation.

- Peak torque: RI60 KV120 (1.63 N·m) minus RI80 V2.0 KV75 (4.1 N·m) = -2.47 N·m.
- Rated torque: RI60 KV120 (0.57 N·m) minus RI80 V2.0 KV75 (1.45 N·m) = -0.88 N·m.
- Maximum speed: RI60 KV120 (5760 rpm) minus RI80 V2.0 KV75 (2430 rpm) = 3330 rpm.
- Mass: RI60 KV120 (155.9 g) minus RI80 V2.0 KV75 (411 g) = -255.1 g.
