A new ½ ATR conduction-convection-cooled enclosure with a unique, advanced airflow design that distributes air across external fins in sidewalls helps to ensure fast removal of dissipated heat, yet still maintain a low profile design. The ½ ATR box from Elma Electronic Systems ships with a 6-slot 3U OpenVPX (VITA 65) backplane on 1” pitch; it is also available with either a 3U cPCI backplane or a single-width MicroTCA backplane. The unit also offers the choice of a fixed mount or plug-in 28 VDC power supply. The unit weighs only 12.5 pounds prior to power supply or payload. 

The all-aluminum ATR is made from milled plates as well as punched and formed sheet metal. The main body is dip-brazed for optimum heat conductivity. The conduction-cooled card cage is completely sealed off to keep the electronic components in a clean environment. A removable front panel allows I/O customization to exact application requirements. Narrow screw spacing ensures high EMC shielding compliant to MIL-STD 461E.  The enclosure meets ARINC 404A and ANSI/VITA 48.2 standards. Pricing for the 1/2 ATR configuration starts at $15,000 in low quantities.
