Dimensions

CEX is provided using an anodized-aluminium enclosure with enhanced EMI shielding.

There are no navigation sensors built into the CEX, which means there are no restrictions on vibration isolation, location or orientation of the CEX.

The following figure shows the dimensions of the enclosure. The mounting holes of the enclosure are 4 mm deep M3 threads.
