Solid state flash memory cards are surprisingly robust in terms of mechanical shock, but show poor resistance to fire and mechanical crushing.
BorgCo engineers have therefore developed an aftermarket SD card enclosure to provide significant crash-resistance to a regular memory card.
The enclosure
has a tough metal outer case, within which further layers of thermal (mineral) and mechanical protection enclose the card and interface. The cable gland is similarly protected against fire and liquid ingress; the unit can survive 1000C fire for 60 minutes, thermal shock, immersion to 1000m, corrosion, and high-G impacts.
The cable terminates in a terminal which will fit into a standard SD or microSD/TF card slot and provided plug-and-play functionality with no loss of transfer speed due to buffering electronics in the case.
The unit allows a cheap action cam to function effectively as a CVR, and even a FDR if the camera is watching the flight instruments.
