Output shaft adds 10 mm to the 32 mm length, and the encoder extends past the 10 × 12 gearbox cross section on three of the four sides. See dimension diagram for details.
D shaft.
Typical; ±20%.
Typical, ±50%; no-load current depends on internal friction, which is affected by many factors, including ambient temperature and duration of motor operation.
This motor will run at 6 V but is intended for operation at 12 V.
