Premium low-noise accurate IMU sensor
Inertial Measurement Units (IMUs) have expanded into fields where precise position, attitude control, and high stability are crucial. The Epson M-G370PDT0, with six degrees-of-freedom sensors, addresses these demands by providing low-noise and high-accuracy measurements.
The M-G370PDT0 matches the M-G370PDS0 with a 0.03°/√h angle random walk and high noise immunity, ensuring precise detection of slight attitude changes. Like the M-G370PDG0, it offers selectable accelerometer output ranges of ±8G or ±16G and features 0.05% non-linearity on the full-scale range of the gyroscopic sensor.
When the IMU is powered on, stored calibration parameters are automatically applied to the measurement data and sent to the application. Finally, the M-G370PDT0 is cross-compatible with the M-G370PDS0/ PDG0 making performance upgrades easy.
