DMU10 Inertial System

6-DOF precision MEMS inertial measurement unit

About the DMU10 Inertial System

The DMU10 combines MEMS angular rate and linear acceleration sensors to create a precision, low-cost, six-degrees-of-freedom (6-DOF) IMU for complete motion sensing and control in three-dimensional space. DMU10 is suitable for a wide range of applications and is available in an OEM form factor, and either uncalibrated (DMU10-01) or calibrated over the full rated temperature range (DMU10-21).
