The IM23TCB is a compact 25 × 25 × 5.9 mm inertial measurement unit (IMU) and controller from FEYMAN.
It is built on the proven IM19 module platform, which is deployed across a wide range of industrial applications, with more than 100,000 units shipped by 2023. The IM23 is the mechanically reinforced, screw-mounted version of the surface-mount IM19, designed for the most demanding industrial environments.
The IM23 combines a six-axis sensor set with a high-performance processor, supporting tilt measurement, RTK imaging and laser survey, agricultural machine control, gimbals and similar applications. Every unit is factory-calibrated across the full temperature range.
