SD201 Low Precision Fiber Optic Inertial Measurement Unit (IMU)

This product is an inertial measurement unit consisting of a small three-axis fiber optic gyroscope and a small quartz accelerometer. It provides three axial angular velocity and acceleration information through the RS422 serial port. It has outstanding features such as small size, light weight, low power consumption, large measuring range and high reliability. It is an ideal choice for IMUs with low precision in the control field.
