Encompassing all standard sizes and combinations of 3U, 6U, 9U and 12U sub-racks, this VME packaging system offers an easy-to-use method for specifying standard or custom VME and Multibus II sub-racks. To speed the design-to-manufacture process, the firm can work directly from CAD file data, with or without support drawings. System software includes Graftek GMS, Pro/Engineer, AutoCAD, IGES and DXF. The sub-racks are made of rugged, stylized aluminum extrusions. All plastic components are molded of flame-retardant UL94V-0 material. A card guide with molded-in loop eliminates the need for additional snap-in pieces in injector/ejector applications.
