Details
A high-torque DS3245SG coreless digital servo with a waterproof housing, supplied with multiple servo horns and mounting screws.
Coreless motor design pairs with a metal gear train for reliable, responsive actuation in RC and robotics builds.
Stainless steel gearing, CNC aluminium middle shell, and sealing gaskets support durability for demanding environments.
PWM control supports a 500–2500 μsec pulse range with JR 3‑pin wiring options, and can be configured for 180° or 270° travel.
