The IIM-46234 is a SmartIndustrial™ 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-46234 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.

    • Highly accurate 3-axis accelerometer
    • Highly accurate 3-axis gyroscope
  • Factory calibration over entire operating temperature range for offset, sensitivity (scale factor), G-sensitivity and cross-axis sensitivity
  • Ultra-low noise sensors that deliver precise measurements, even in harsh environments
  • Micro-second time stamps with all sensor measurements for accurate timing transfer
  • Temperature output
  • Supports SPI and UART
  • Temperature range: -40C to 85C
  • 23 x 23 x 8.5mm Module with a 20 pin connector

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
