Pin pullers are used to hold, lock or secure deployable or moving parts on spacecrafts during their launching. These ‘one shot’ actuators used to be based on explosive charges. Pin pullers important characteristics are their retraction force that needs to be sufficient to pull the pin out of the locking mechanism, their maximum radial force, which limits the size of the secured system, and their dimensions and weight. The possibility of resetting the mechanism is also an appreciated advantage. Upon request of CNES, the French National Space Agency, CEDRAT TECHNOLOGIES has designed a resettable electromagnetic actuated pin puller, called BRUCE
