Pin Pullers

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 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. Therefore, it can be concluded that pin pullers are critical devices to enable the proper operation of any spacecraft using them.
