During the presented project a compact, low weight, low shock and cost-efficient pinpuller for space applications based on thermo-mechanical release mechanism has been developed, manufactured and tested by RUAG Space Germany (RSG). As an alternative to current devices, the new developed RSG pinpuller, called LIP500, is able to work in a wider range of temperatures, such as from -70ºC to 100ºC and under vacuum conditions. On top, this release device allows multiple resets with a minimum effort. Up to now the built qualification models of the pinpuller did undergo different tests and analysis in order to elaborate the maximum force and life time by the mechanism components of the device. Test conduction and results of the qualification campaign will be presented with focus on deviations from the expected behaviour and on lessons learned. Especially investigations on the shock generation of the pinpuller as well as the reliability will be presented.
