30:1 metal geared motor 37Dx68L mm with encoder

This geared motor is a high-performance 12V brushed DC motor with a metal gearbox offering a 30:1 gear ratio and an integrated quadrature encoder with a resolution of 64 pulses per revolution (CPR) on the motor shaft and 1920 CPR on the gearbox output shaft. The gearbox consists primarily of spur gears, but features helical gears in the first stage to reduce noise and improve efficiency. These units have a 16mm long, 6mm diameter D-shaped output shaft.
