  • Voltage (Nominal): 12V
  • Voltage Range (Recommended): 6V - 12V
  • Speed (No Load @ 12VDC): 84 rpm
  • Current (No Load @ 12VDC): 0.53A
  • Current (Stall @ 12VDC): 20A
  • Torque (Stall @ 12VDC): 1347 oz-in (97 kgf-cm)
  • Gearbox Style: Planetary
  • Connector Type: PH Series JST 6-pin Connector (2mm Pitch)
  • Encoder Cycles Per Revolution (Motor Shaft): 12
  • Encoder Countable Events Per Revolution (Output Shaft): 4,776.384
  • Gear Ratio: 99.508:1
  • Encoder Type: Relative, Quadrature
  • Encoder Sensor Type: Magnetic (Hall Effect)
  • Encoder Sensor Input Voltage Range: 2.4 - 26V
  • Encoder Sensor Output Pulse Amplitude: ~= Sensor Input Voltage


The pulse amplitude of the encoder’s output square wave signal is dependent on the voltage you supply the sensor. For example, if you provide 5V to Sensor Voltage +, then Channels A & B will have a pulse amplitude of 5V.

To enhance the resolution, the encoder is attached to the motor before the gearbox.

Gear train damage can occur if stalled (locked).
