Overview:

These brushed DC gearmotors have a diameter of 25mm (0.984 inches) , with all versions available with an integrated quadrature encoder on the motor shaft. The 12V motors provide roughly the same performance at their respective rated voltages.Its motor shaft is a 4mm D-shaft.

These motors can typically be run at voltages above and below their rated voltage, with lower voltages being less practical and higher voltages beginning to have a negative impact on the motor's lifespan.

The gearboxes are primarily made up of spur gears, but their first stage uses helical gears to reduce noise and increase efficiency.

Using the Encoder:

The motor encoder has six colored, 8-inch (20 cm) leads with a 1×6 female header on the end with a 0.1″ spacing, as shown in the main product picture. The header pins can be used with a plug. If this plug is not convenient for your application, you can pull the wires out of the plug or cut off the plug. The table below describes the function of each wire.
