Tronics Microsystems, a TDK Company

Tronic’s Microsystems S.A. is a high performance MEMS inertial sensors supplier established in Grenoble, France in 1997. After a successful international growth we were introduced on the Euronext stock market in 2015 (ticker symbol ALTRO). We are now proud to be majority-owned by TDK since 2017 and to be part of TDK Sensors Systems Business Company.

We operate a MEMS production facility in Crolles, near Grenoble since 2003. We had made an early commitment to quality and we have been ISO9001 certified since 2001. Since our acquisition by TDK we have further reinforced our Corporate Quality Policy. We are now IATF16949 certified since 2019, and our ISO14001, ISO45001 and ISO50001 certification now also recognize our commitment to reducing our impact on the planet. As a proud member of TDK we also follow the Sustainability rules.
