TDK Launches Fault‑Tolerant InvenSense IMUs for Industrial Applications

TDK Corp. has unveiled a new line of fault‑tolerant InvenSense inertial measurement units (IMUs) designed for demanding industrial settings. The ultra‑low‑noise IIM‑46234 and IIM‑46230 models feature integrated 6‑axis sensors that deliver precise measurements of linear acceleration and angular rate across all three dimensions.

With a gyroscope bias instability of only 1.9 deg/hr and microsecond‑level time‑stamping, the IMUs offer exceptional accuracy in challenging environments. Factory calibration across the full operating range of –40 °C to 85 °C ensures reliable offset, sensitivity, G‑sensitivity, and cross‑axis performance.

The new family incorporates TDK’s proprietary SensorFT technology, combining a multi‑IMU hardware architecture with intelligent fault‑detection and recovery software. This integrated redundancy gives engineers early warning of sensor anomalies and automatic recovery, enhancing system reliability.

Designed to withstand vibration and wide temperature swings, the IIM‑4623X series is ideal for navigation and stabilization in precision agriculture, construction machinery, unmanned aerial vehicles, and industrial robots.

For instance, a construction vehicle can fuse IIM‑4623X data with GPS to obtain real‑time position, attitude, and motion. Such instant information boosts automation, efficiency, and safety for mobile industrial equipment, according to TDK.

Customers can pair the IMU family with InvenSense’s Coursa Drive software to deploy a turnkey inertial navigation system (INS) with minimal development effort and cost.

The IIM‑46234 and IIM‑46230 are now available to select early partners and customers. TDK will showcase the new line at CES 2020 in booth #11448, Central Hall (LVCC).
