About
The Retractable Mast Mechanism is a linear electromechanical device specifically engineered for the deployment of umbrella-type deployable reflectors from their stowed transportation position to their operational configuration, followed by their secure fixation. This mechanism was first released in 2005 and boasts a guaranteed service life of 10 years. It offers precise positioning with an accuracy of 0.1 mm and can operate within a temperature range of -40 to +50 °C. The operational life is defined by 50 cycles, and it has an active lifetime of 10 years, with an overall guaranteed lifetime of 14.5 years. The mechanism generates a force not exceeding 2500 N and has a mast retraction time of 30 minutes. Its overall dimensions are 252 x 252 x 4100 mm, and it has a mass of 12 kg. Estimated production and delivery time is 6 months.
