The SG92R is the upgraded SG90: identical 9g body, identical 3-wire wiring, identical horns and mounting holes, but with carbon-fibre reinforced gears and 25 to 40% more torque. It is a positional servo with a 90° half sweep, running between the 90° and 180° marks on the standard servo scale, so you command an angle and it moves there and holds it. Choose it over the plain SG90 when a build keeps chewing through gears, or when you want tighter centring and a smoother sweep.
- 9g micro servo, runs on 4.8-6V
- Carbon-fibre reinforced gears, tougher than the SG90's plain nylon
- Roughly 2.2 to 2.5 kg/cm torque at 4.8V, 25-40% more than the SG90
- 90° half sweep, positional: command an angle and it holds it
- Standard 3-wire 50Hz PWM, works with the Arduino Servo library
- Includes three servo horns and mounting screws
- Tighter deadband for better centring and smoother movement
- Hand-tested before dispatch from our Te Awamutu workshop
SG92R or SG90?
SG92R - the stronger one
Same body, same wiring, same horns, different internals. Carbon-fibre reinforced gears, roughly 2.2 to 2.5 kg/cm at 4.8V, a tighter deadband and better resistance to stripped gears. Best for robotics, pan and tilt rigs, RC control surfaces and anything that gets driven hard or run often.
SG90 - the budget one
Plain nylon gears and roughly 1.6 to 1.8 kg/cm at 4.8V. Perfectly good for light-duty and occasional use: latches, small levers, camera tilt and short repeatable arcs. If a build has already stripped one of these, step up to the SG92R.

Great for
Wiring & code
- Brown = GND, Red = V+, Orange = signal to a PWM pin (e.g. D9)
- Use the built-in Arduino Servo library, no extra drivers needed
- servo.write(angle) sets the position, with the usable band running about 90 to 180
- Anything below 90 simply parks it against the low end stop
- Sweep it slowly the first time to find where the ends sit on your unit
- Under load, power from a dedicated 5V supply with a common ground
Good to know: every servo is hand-tested before it leaves our Te Awamutu workshop, checked for a smooth sweep across its full travel and clean centring. Driving past the mechanical stops will make any servo buzz and wear, so keep your commanded angles inside the band. Stocked in NZ and dispatched fast, overseas prices without the overseas wait.
