TDK InvenSense IIM-4623x 6-Axis MotionTracking® MEMS Devices

TDK InvenSense IIM-4623x SmartIndustrial™ 6-Axis MotionTracking® MEMS Devices combine multiple 3-axis gyroscopes and 3-axis accelerometers into a single high-performance device. The 6-axis industrial IMUs offer 1.9°/hr (IIM-46234) or 4.1°/hr (IIM-46230) gyroscope bias instabilities, fault tolerance, and micro-second accurate time stamping features. Using ultra-low noise sensors, IIM-46234 and IIM-46230 deliver precise measurements, even in harsh environments. The TDK InvenSense IIM-4623x devices operate within a 3.0V to 3.6V voltage range and a -40°C to +85°C temperature range.

Features

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 (2000g survivability) 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
-40°C to +85°C operating temperature range
Factory calibration over temperature range for bias, sensitivity, misalignment, and G-sensitivity
Dynamic correction of the output of Accelerometer and Gyroscope measurements with user-configured bias, sensitivity, and misalignment values stored in the device
