Industrial IMU delivers high stability

TDK Corp. has extended  its InvenSense SmartIndustrial sensor platform family with the introduction of the IIM-20670 six-axis IMU. Consisting of a three-axis accelerometer and three-axis gyroscope, the MEMS industrial IMU offers high stability, high vibration immunity and the capability to simultaneously measure all six axis with a current consumption below 10 mA under all operating conditions.

Targeting industrial applications that require “extreme” stability over temperature and high vibration immunity, the IIM-20670 is calibrated over multiple temperature points and offers an extended temperature range of -40°C to 105°C. It also claims high vibration rectification error (VRE) performance.

The industrial IMU provides an accelerometer thermal stability of 45 ug/C, an accelerometer bias repeatability of 1 mg and a programmable output of 64 G together with a tilt algorithm that outputs pitch and roll data over the full temperature range. Gyroscope thermal stability is 1.7 mdps/C. Other key features include an operating voltage range of 1.71 to 3.6 V, programmable digital filters and a 10-MHz SPI interface with a CRC-based error-detecting code algorithm.

TDK said these specifications allow the IIM-20670 to provide one of the most stable six-axis tilt outputs in the industry and makes them well suited for applications that need fast and accurate tilt or stabilization performance such as 5G platforms, industrial tilt modules and industrial/agricultural drones.

The IIM-20670 is housed in a QFN package, measuring 4.5 x 4.5 x 1.1 mm with wettable flanks that simplify inspection at the end of the assembly line. The IIM-20670 platform is available for evaluation and through distribution partners worldwide by the end of July 2023.

TDK is demonstrating the IIM-20670 at Sensors Converge 2023, June 20-23, in booth #992 at the Santa Clara Convention Center. A full range of sensor system solutions also will be on display for applications across automotive, consumer, health, industrial, machine learning and robotics.
