Compatibility and use Designed for miniature/mechatronic systems that require compact size, encoder feedback, and dependable torque. Suitable for hobby electronics, small robotics, pan-tilt mechanisms, model automation, and light-duty actuators. Practical application examples Mobile robot drive: Use the 1218GE-N20 on compact mobile robots where encoder feedback improves speed regulation and navigation accuracy. Camera pan-tilt or gimbal: Low-noise metal gears and stable transmission provide smooth, repeatable motion for small camera mounts. Small robotic arm or gripper: Wide torque options let you select a speed/torque balance appropriate for precise pick-and-place or light manipulation tasks. Installation and operation notes Operate at the specified nominal voltages (3 V or 6 V) corresponding to the performance option chosen. Choose the speed/torque option that matches your load requirements; higher torque options will yield lower no-load speeds. The encoder provides feedback for closed-loop control; integrate with appropriate motor drivers and controllers for best performance.
