Notes:
- 1
- 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.
- 2
- D shaft.
- 3
- Typical; ±20%.
- 4
- Typical, ±50%; no-load current depends on internal friction, which is affected by many factors, including ambient temperature and duration of motor operation.
- 5
- This is a theoretical value; stalling the gearbox output shaft could damage the gearbox.
