The PTK 8862 is a heavy-duty high-torque waterproof digital standard servo designed for demanding RC, robotics and motion-control applications. It features a powerful brushless motor, durable stainless steel gears, waterproof plastic housing and a full CNC middle case for strength and reliable operation.
Operating from 5.0V to 8.4V, the PTK 8862 delivers up to 72kg.cm stall torque at 8.4V with a speed of 0.105 sec/60°. Its 1520μs / 333Hz digital control frequency and 2μs dead band help provide responsive and precise positioning.
The servo includes dual ball bearings, a 6mm 25T output spline, high-precision potentiometer, side wire outlet and 300mm cord. Its 40 × 20 × 40.4mm standard-size body makes it suitable for high-load RC steering, robotic arms, automation mechanisms and other applications requiring powerful servo control.
