IEC 60297

The IEC 60297 series of standards specifies the mechanical structure of printed circuit boards, subracks and racks in 19" design in the various subdocuments.

The IEC 60297 series of standards specifies the 19" assembly system as a standardized modular system. In this series of standards, the complete system is divided into several levels. Thus, level 1 stands for components such as printed circuit boards, level 2 for subassemblies, level 3 for subracks and level 4 for racks for holding the subracks. This standard is all about the mechanical structures, height, width and depth dimensions. Although the structure was originally defined as 19" and is specified as such, the dimensions for plug-in boards and subracks are specified in the metric system.

IEC 60297: This standard is the basic standard for 19" construction. The specification of 19" at 25.4 mm for one inch in the metric system corresponds to 482.6 mm.

IEC 60297-1: Standard 60297-1 deals with front panels and rack sizes. The size specifications should be considered in conjunction with the cabinet dimensions and insert panels discussed in the following standard.

IEC 60297-2: This sub- document deals with cabinet dimensions, grid sizes for subracks, external trim for racks, doors and supporting elements.

IEC 60297-3-101: This part document describes the dimensions for modular subracks and the printed circuit boards that can be inserted into them.

IEC 60297-3-102: Subdocument 3-102 supplements the previous one with mechanical devices for the extraction and insertion of printed circuit boards.

IEC 60297-3-103: And the last sub-document specifies the coding devices, guide pins and guide rails.
