12R2 Design Features

The 12R2 rugged COTS design combines extruded profiles and the rugged benefits of standard aluminum frames and captive hardware. This innovative designbases the entire chassis around the custom ruggedized side plate. Spot-welded to a 3mm thick aluminum plate are front, rear, top and bottom extruded aluminum profiles. The flexibility of the extrusions allows modification of the entire chassis with standard, off-the-shelf aluminum frames, ensuring quick delivery and minimal engineering effort. The final product is a shell that can and has easily passed MIL-STD-810F, MIL-STD-167 and MIL-STD-901D shock andvibration tests. The coverset is 3mm thick and has custom, stainless steel, captive screws installed. Each mating extrusion has an EMC gasket channel and a T-channel thataccommodates the rugged stainless steel tapped strip. The 4mm thick rear frame is designed to give maximum available I/O space for each size; each chassis comes with a standard 1.5mm thick blank patch panel. For corrosion resistance, every aluminum part in the 12R2 chassis has a protective yellowchemical conversion coating per MIL-C-5541E Class 3.The 12R2 offers a superior EMC package. Designed to meet EMI requirements per MIL-STD-461D, the 12R2 uses MIL grade EMC line honeycomb filters,braided gasketing, and metal impregnated flat gaskets to seal off every external seam.The 12R2 integrates COTS MIL-grade components and a standard wire harness to ensure a high quality, rugged electrical turnkey system without the associated engineering and delivery problems common in today’s COTS market. The harnesses and components have been designed and selected to maximize the system options from standard configurations.
