IIM-46230

The IIM-46230 is a 6-axis MotionTracking device that combines multiple 3-axis gyroscopes and 3-axis accelerometers packaged in a module that is approximately 23 × 23 × 8.5 mm and includes a standard 20 pin connector interface.

The IIM-46230 includes multiple capabilities to enable easy, robust and accurate inertial measurements in Industrial applications:

TDK proprietary SensorFT™ (Fault Tolerance) feature that delivers built-in redundancy and early warning
Low bias instability
Low offset and sensitivity variation over temperature
Robustness to shock and vibration
Triaxial, delta angle and delta velocity output
Accurate timestamps, which can be set to UTC timestamp and synchronized to an external PPS pulse
Operating temperature range: -40°C to 85°C
Factory calibration over temperature range for Bias, Sensitivity, misalignment, G-sensitivity
Dynamic correction of the output of Acceleromer and Gyroscope measurements with user configured bias, sensitivity and misalignment values stored in the device

The device features an operating voltage range from 3.6V down to 3.0V.

Advantages

High performance module that includes multiple 6-Axis MEMS Gyroscopes and Accelerometers and delivers low bias instability, ARW and VRW
TDK’s unique SensorFT™ feature delivers built-in redundancy and early warning against individual sensor failures
Factory calibration over for offset, sensitivity (scale factor), G-sensitivity and cross-axis sensitivity enables accurate measurements across entire operating temperature range

These modules also include TDK’s unique SensorFT™ feature that delivers:

Built-in redundancy: The module can tolerate one or more failures of its active components without complete failure
Early warning: The module provides status indicating changes in its performance, thus providing an early warning to the user, before the module fails completely.
Enhanced lifetime and reliability
