The Pololu 100:1 Micro Metal Gearmotor LP 6V w/ 12 CPR Encoder, Side Connector is a compact brushed DC motor featuring a robust metal gearbox with a cross-section of 10×12 mm. It is equipped with 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 (CPR) of the motor shaft, which can be multiplied by the gearbox reduction factor to determine the counts per revolution of the gearbox output shaft.

The encoder is connected via 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 through red and black wires when used with appropriate JST cables, with M1 always connecting to the motor terminal marked with a “+”. The motor is designed to operate in both directions by alternating the polarity of the power to the motor leads.

The sensors are powered through Vcc and GND pins, with Vcc ranging from 2.7 V to 18 V. The quadrature outputs A and B are digital signals that indicate motor direction and speed, with built-in hysteresis to prevent spurious signals. The motor operates at a low power of 6V with precious metal brushes, achieving a no-load performance of 130 RPM at 40 mA.
