| 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.

EC-A3814-H14-107: Unverified catalog: confirm sources. 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.

FHA-14C-100 (FHA-C Mini): Catalog headline specs spot-checked: confirm revision.

## 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: EC-A3814-H14-107 (60 N·m) minus FHA-14C-100 (FHA-C Mini) (28 N·m) = 32 N·m.
- Rated torque: EC-A3814-H14-107 (20 N·m) minus FHA-14C-100 (FHA-C Mini) (6.8 N·m) = 13.2 N·m.
- Maximum speed: EC-A3814-H14-107 (52 rpm) minus FHA-14C-100 (FHA-C Mini) (60 rpm) = -8 rpm.
- Mass: EC-A3814-H14-107 (434 g) minus FHA-14C-100 (FHA-C Mini) (1650 g) = -1216 g.
