The Pololu 250:1 Micro Metal Gearmotor LP 6V w/ 12 CPR Encoder, Side Connector is a compact brushed DC motor equipped with a metal gearbox. It features a 10×12 mm gearbox cross-section and a 9 mm long, 3 mm diameter D-shaped output shaft. This gearmotor integrates a two-channel incremental Hall effect encoder, which detects the rotation of a magnetic disk on the motor shaft's rear protrusion. The encoder provides a resolution of 12 counts per revolution of the motor shaft, with the gearbox output counts determined by multiplying this by the gearbox reduction factor.

The encoder is equipped with a 6-pin JST SH-style male connector, compatible with corresponding cables and connector boards. The side connector orientation is perpendicular to the motor. The motor terminals are accessible via red and black wires when used with appropriate JST cables, with M1 consistently connecting to the motor terminal marked with a "+" on the back of the motor case. The sensors are powered through Vcc and GND pins, with Vcc ranging from 2.7 V to 18 V. Quadrature outputs A and B provide digital signals, driven low or pulled to Vcc, depending on motor orientation. These signals are square waves with 50% duty cycles and are approximately 90° out of phase, indicating motor direction and speed.

Note: A cable is not included with this gearmotor.
