ESD Compliance:
The MXR7305V sensor is in compliance with the following ESD
standards:
Human Body and 2500V per AEC-Q100-002 Rev. E
Machine Model and 250V per AEC-Q100-003 Rev. E
Mounting Orientation:
The package orientation of the MXR7305V does not affect the
performance of the sensor. The specifications as stated in page 2
remain the same.
Thus, if the sensor is installed with one of its axis of sensitivity in
the vertical plane, it detects accelerations in the Z-axis.
