Description
MEMS Inertial Measurement Unit

MOQ: 1
Size: L(4.7) * W(4.4) * H(1.4) cm
Specification Number: LKF-MSU204A

The LKF-MSU204A MEMS is a compact, high-precision 9-axis inertial measurement unit (IMU), designed for high-precision navigation, control and dynamic measurement of carriers. This inertial measurement module integrates MEMS gyroscopes, MEMS accelerometers and MEMS magnetometers within a single housing. Adopting highly reliable MEMS sensors, it can accurately measure angular rate, acceleration and magnetic field information of moving carriers under harsh environments, making it a general-purpose device for industrial applications.
The LKF-MSU204A inertial measurement module adopts an aluminum alloy housing, which is lightweight with high structural strength and excellent anti-vibration & anti-shock performance.
