Murata SCH16T-K30 IMU for High-Vibration Industrial Applications
Murata Manufacturing Co., Ltd. has expanded its SCH16T series of high-performance inertial measurement units (IMUs) with the introduction of the SCH16T-K30. This new variant is specifically designed as a high-dynamic-range sensor for demanding industrial applications where high-amplitude vibration or rapid movement can cause traditional sensors to saturate or clip.
In environments such as excavators, heavy machinery, and surveying equipment, inertial sensors are exposed to strong mechanical vibration in addition to the motion they are intended to measure. The SCH16T-K30 addresses this challenge by preventing sensor output saturation, thereby ensuring accurate capture of machine motion even under extreme conditions. Samples of the SCH16T-K30 are currently available, with mass production scheduled to commence at the end of 2026. The product will also be showcased at electronica 2026 in Munich, Germany.
The SCH16T-K30 differentiates itself through a new MEMS accelerometer with increased damping characteristics, designed to attenuate unwanted vibration at frequencies above 200 Hz. It also features an extended gyroscope measurement range and a high saturation limit, providing additional headroom for higher rotational dynamics and robust performance in high-vibration environments.
