SBS Technologies, represented by Metromatics , has introduced the RCOM05-ATR-6V standard 1/2 ATR short ARINC-404 chassis designed to meet the strict space limitations of the ARINC-404A envelope used in most avionics applications.

The lightweight aluminium chassis is cooled by convection or via a base cold plate, which results in excellent thermal performance and allows a maximum temperature range of -40°C to +71°C.

The chassis houses a five slot 6U VME64X backplane accommodating up to five top loaded conduction cooled 6U VME boards, including power supply, and a 300W 28V dc plug-in power supply that is MIL-STD-740D and MIL-STD-461C compliant.

The chassis' removable surfaces are provided with environmental/EMI gaskets, which protect internal electronic assemblies from airborne contaminants.

The chassis is sealed creating a dry air environment with all boards, including the power supply secured with wedge locks to enhance resistance against shock and vibration.
