SG92R Micro Servo 180 Degree (Nylon Gear)
The SG92R Micro Servo 180° (Nylon Gear) is a lightweight, high-speed, and cost-effective servo motor designed for precision positioning tasks in compact electronics and robotics projects. Known for its reliability and efficiency, the SG92R is an upgraded version of the popular SG90, offering better performance and improved materials while maintaining the same small form factor.
This servo is capable of rotating up to 180 degrees, making it suitable for a variety of applications that require accurate angular movement, such as robotic arms, pan-tilt camera systems, remote-controlled aircraft, and animatronics. It uses high-quality nylon gears, which provide a good balance between strength and smooth operation, making it quieter and more lightweight compared to metal gear alternatives. Though not as strong as metal gears, nylon gears are excellent for low-load applications and are more resistant to sudden shock loads.
The SG92R operates on a standard 4.8V to 6.0V DC power supply and responds to PWM signals for precise control. The typical pulse range is from 1 ms to 2 ms, where 1.5 ms corresponds to the neutral (90°) position. This servo motor features a coreless motor design, which offers faster response time, higher efficiency, and less vibration than traditional cored motors.
With its three-wire standard servo connection—signal, power, and ground—the SG92R is compatible with most microcontroller platforms like Arduino, Raspberry Pi, and other robotics controllers. It is widely used in hobby electronics, educational kits, and DIY automation systems due to its affordability, ease of use, and broad availability.
Overall, the SG92R Micro Servo 180° is a practical and reliable choice for projects that demand smooth, precise angular movement without the need for high torque or metal gear durability.
