25GA370 DC Gear Motor With Encoder 200RPM 12Vdc

25GA370 DC Gear Motor with Encoder is a compact, high-torque motor designed for robotics and automation. It combines a 25mm gearbox with a 370-size DC motor and a built-in encoder for speed/position feedback. With 200RPM at 12VDC, it’s ideal for smart robots, line followers, AGV projects, and precise motion control applications.
