Mechanische Bauweisen für elektronische Einrichtungen - Maße der 482,6-mm-(19-in-)Bauweise - Teil 3-109: Maße von Einschüben für eingebettete Datenverarbeitung (IEC 60297-3-109:2015); Deutsche Fassung EN 60297-3-109:2016
Overview
This standard specifies the dimensions and requirements of chassis for embedded systems used primarily in machine control, aerospace, and telecommunications applications. Single-board computers are commonly used in such applications. Adapted enclosures are needed in order to meet the different environmental and handling requirements. These provide the characteristics for the required mechanical protection and adaptation to the environment at the location of the intended application. For the easy definition of the suitable chassis and associated single board dimensions, this standard is based on a structural grid of 44,45 mm. This grid provides the necessary flexibility for design and for cost-optimized manufacturability. The responsible committee is DKE/K 662 "Bauweisen" ("Mechanical structures") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
