DC Motorized Potentiometers

The MC and ME Series perform best at low (5-20ma) currents. Choose from 6, 12 or 24 VDC and 1, 3, 5, 10, 18, 35, 61, or 120 RPMs with other RPMs available. (RPM’s are +/- 20%). Two Six (6”) inch lead wires are attached to the motor — one red and one black.

  • Resistances values are 10, 20, 50, 100, 200, 500 ohms, 1K, 2K, 5K, 10K, 20K, 50K, and 100K depending on model.
  • Diagrams available by email – Length measurement depends on RPM’s required and therefore the motor and geartrain used.
  • Length can vary +/- .5 inch depending on motor and geartrain used to get the correct RPMs.
