Industrial Grade MEMS IMU. Designed with robust applications in mind, the IMU20 has excellent dynamic range and is suitable for the highest impact and vibration environments.

IMU20™ is a compact six-degree of freedom inertial measurement unit providing precise outputs of angular rate, acceleration, and temperature. With high levels of shock survivability, IMU20™ is designed specifically to meet the growing needs from the high-end commercial and industrial market applications for a high performance, rugged, non-ITAR IMU. It is a viable alternative to more costly ‘FOG-grade’ IMUs, particularly in markets such as satellite launch vehicles and similar exacting motion sensing applications.

The IMU20 utilises our class-leading MEMS inertial sensors and is calibrated using an in-house state-of-the-art test facility.
