Murata inertial sensor has six degrees of freedom for industrial equipment
MOYA-TECH 2021-02-24
The six-degrees-of-freedom sensor is called SCHA63T and includes X, Y and Z-axis angular rate sensors and a three-axis accelerometer based on capacitive MEMS.
Signal processing is done with two mixed signal ASICs that provide angular rate via an SPI digital interface.
It offers “gyro bias instability down to the 1°/h level and gyro noise density of 0.0015°/s/√Hz”, according to the company. “Cross-axis calibration enables better than 0.14° orthogonality error.”
Additional features include user-selectable filter settings of 13, 20, 46 or 300Hz, and self-diagnostics for safety-critical applications.
operation is over -40°C to +110°C and 3.0V to 3.6V.
Packaging is in a pre-moulded 20 x 12 x 4.6mm SOIC 32 plastic housing
Applications are foreseen in IMUs (inertial measurement units), machine control, machine guidance, robot control and UAVs.
