| Rated torque (catalog) | 30 N·m | 40 N·m |
| Maximum speed (catalog) | 60 rpm | 200 rpm |
| Mass | 660 g | 1420 g |
| Gear ratio | 48:1 | 9:1 |
| Voltage | 24-48 V | 15-60 V |
| Price (catalog, not a live quote) | 265 USD | 255 USD |
| Encoder (resolution is not accuracy) | dual 16-bit magnetic single-turn encoders (motor and output) | dual magnetic |
| 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: DM-J6248P-2EC (97 N·m) minus RobStride 04 (120 N·m) = -23 N·m.
- Rated torque: DM-J6248P-2EC (30 N·m) minus RobStride 04 (40 N·m) = -10 N·m.
- Maximum speed: DM-J6248P-2EC (60 rpm) minus RobStride 04 (200 rpm) = -140 rpm.
- Mass: DM-J6248P-2EC (660 g) minus RobStride 04 (1420 g) = -760 g.
