Our Company History

SONDEV administration and mechanical design

SONDEV development and test center

DIN ISO 9001 Certificate

The history of SONDEV reaches back before its founding in 2008: as early as 2003, initial developments in sensor and measurement technology were carried out in the environment of SONTEC Sensorbau GmbH.


In 2025, SONDEV was fully integrated into SONTEC Sensorbau GmbH. Since then, the SONDEV brand has encompassed SONTEC’s central development unit. For customers and partners, this means more synergies, shorter lines of communication, and a broader range of services—from concept and design through to series production.
