MXC6245XU

  • Overview
  • Specifications
  • Features and Benefits

The MXC6245XU is a complete 2 axis accelerometer system with 1mg resolution, very low 0g offset drift, and excellent sensitivity matching. The internal status of the sensor can be read via the I2C interface.
The MXC6245XU uses MEMSIC’s proprietary thermal accelerometer technology. Because the sensing element uses heated gas molecules instead of a mechanical beam structure, the device is extremely robust and reliable, with 50000g shock tolerance, no possibility of “stiction,” virtually no mechanical resonance, and very high accuracy over temperature. This makes the device extremely well suited to harsh or high-vibration environments, where other sensors can exhibit false readings due to resonance or other errors
