The PTK 6820 MG is a high-speed waterproof digital standard servo built for RC cars, robotics and precision motion-control applications. It features metal gears, a core motor, dual ball bearings, waterproof housing and a 6mm 25T spline for durable and responsive performance.
Operating from 4.8V to 8.4V, the servo delivers up to 27kg.cm stall torque at 8.4V with a fast speed of approximately 0.087 sec/60°. Its 1520μs / 333Hz digital control frequency and high-precision potentiometer help provide accurate and stable positioning.
With a compact 40 × 20 × 35.5mm standard-size body, 53g weight, side wire outlet and 300mm harness, the PTK 6820 MG is suitable for RC steering systems, robotic arms, automation projects and other high-speed servo applications.
