High Accuracy MEMS IMU with 3-Axis Gyroscope Accelerometer Magnetometer & Barometer
The 16488HB 6-axis inertial measurement unit provides precise motion data for autonomous vehicle and automated guided vehicle (AGV) navigation. Integrating a 3-axis gyroscope, 3-axis accelerometer, magnetometer, and barometer, it delivers comprehensive dead-reckoning capability with 0.8 deg/h gyro bias stability. SPI at 2460Hz and CAN interfaces enable straightforward integration with vehicle controllers.
Product Features
- 6-axis sensing (3 gyro + 3 accel) with magnetometer and barometer
- 0.8 deg/h gyro bias stability for reliable dead-reckoning
- 0.06mg accelerometer bias for precise velocity estimation
- SPI (2460Hz) and CAN for vehicle control unit integration
- Operating temperature -40 to +70 deg C for warehouse to outdoor use
- 50g weight with 20000h MTBF for continuous vehicle operation
