We are looking for a servo/attenuator that can be used to rotate something 90 degrees and then return to start positon, ie something that closes the open door but doesn’t open it.

It needs to be very quick and quite powerful. Looking for something between 7.2v -12v dc

Before we can suggest product types, we could use some additional information about the project itself, how you want to control the actuator, the torque / RPM you want and more. While we await your reply:
