IP67

Rugged M-G552 series and M-G570PR

Precise motion data from one compact module

An IMU combines three gyroscopes and three accelerometers and measures angular rate and acceleration on all axes. Navigation filters and controllers turn this into attitude, heading, velocity and position.

Epson IMUs are factory-calibrated over temperature and output digital data via UART/SPI, RS-422, CANopen or J1939. AMCORIS supplies the complete range and supports you from selection and evaluation to integration.

QUICK ANSWER

Which Epson IMU do I need?

Start with performance: gyro bias instability ranges from 3 °/h (M-G330PDG) down to 0.5 °/h (M-G570PR). Then choose interface and housing: compact UART/SPI modules for embedded boards, IP67 M-G552 units with CANopen, J1939 or RS-422 for vehicles and machines. For functional safety, the M-G355QDG complies with IEC 61508 SIL 1.

SPOTLIGHT

PDG series: one footprint, three performance levels

M-G330PDG, M-G366PDG and M-G370PDG share the same 24 × 24 × 10 mm package and UART/SPI interface, so you can move between performance levels with minimal design changes. For high-end gimbals, the M-G370PDT halves the angle noise.

FAQ

Frequently asked questions

Your question is not listed?

Ask our engineers →

QWhat is the difference between an IMU and a gyro sensor?

A gyro sensor measures angular rate. An IMU combines three gyroscopes and three accelerometers in one calibrated module and provides everything needed for attitude and navigation.

QWhat do bias instability and angular random walk mean?

Bias instability describes slow drift of the gyro offset and limits how well heading is held over time. Angular random walk describes short-term noise and affects how smooth the angle estimate is.

QWhich interface should I choose?

UART/SPI for compact controllers and robots, RS-422 for long cables, CANopen or J1939 for vehicles and machines.

QCan I test the sensors before ordering?

Yes. Request an Epson evaluation kit from AMCORIS and test the sensor in your own setup. Our team helps you choose the right model.

Not sure which IMU fits?

Tell us about your application. We recommend a model and provide an evaluation kit for testing in your own system.
