Bauweisen für elektronische Einrichtungen - Maße der 482,6 mm-(19-Zoll-)Bauweise - Teil 3-107: Maße von Baugruppenträgern und Baugruppen, kleiner Formfaktor (IEC 60297-3-107:2012); Deutsche Fassung EN 60297-3-107:2012
Overview
This standard defines the interface dimensions between subracks and associated plug-in units using connectors as defined in PICMG-MTCA.0 (fixed board) and IEC 61076-4-116 (two part). It describes an alternative/smaller form factor of plug-in units as defined in IEC 60297-3-101. New technologies requiring smaller plug-in unit form factors used in 19 inch equipment practice are rapidly gaining acceptance. Recognizing this development it became obvious that a generic interface standard would be an advantage to the industry. The standard is based upon and coordinated with the plug-in unit form factor as defined in AMC.0 and MicroTCA developed by PICMG (PCI Industrial Computers Manufacturer Group). By making critical interface dimensions available and permitting the use of alternative connectors to the industry (beyond AMC.0 and MicroTCA) multiple product solutions may make use of this technology and will increase the overall market acceptance, increase availability, and reduce cost. The responsible committee is K 662 "Bauweisen" ("Mechanical structures") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
