Mechanical systems

SENER began its space odyssey by developing structural mechanisms and parts. Today, it is a key supplier of electromechanical components and systems for the European Space Agency (ESA) and its principal provider of boominstruments and deployable booms.  

The company has more than half a century of experience in the design,manufacture, testing and final integration of electromechanical components and systems that are critical in space missions, with a track record of 100% reliability, as in all its history of space projects, not one of the more than 275 pieces of equipment supplied by SENER to space programs have ever recorded any faults.

SENER provides several types of electromechanical components and systems:

Rotary actuators

Rotary Actuators for space applications. DTA 1300 series.
