Pin Pullers are linear actuators in which a pin or piston initially remains firmly locked in extended position and, when activated, retracts inside a mechanical structure, usually against a side load. In the extended position, the pin blocks a mobile/deployable element in a spacecraft before it is released for regular operation.
Pin pullers are critical devices widely used in space. Some typical applications include hold-down and release of deployable parts such as solar panels, antennas, booms and masts, stage separation, cover doors, heat shields, instruments or any other payloads.
