Mechanical structures for electronic equipment - Dimensions of mechanical structures of the 482,6 mm (19 in) series - Part 3-107: Dimensions of subracks and plug-in units, small form factor

IEC 60297-3-107:2012 defines the interface dimensions between subracks and associated plug-in units using connectors as defined in PICMG-MTCA.0 (Fixed board, see Figure 7) and IEC 61076-4-116 (Two part, see Figure 12) and other two part connectors, (see Figure 15). For mechanical and climatic tests refer to IEC 61587-1. For electromagnetic shielding performance tests refer to IEC 61587-3.

Structures mécaniques pour équipements électroniques - Dimensions des structures mécaniques de la série 482,6 mm (19 pouces) - Partie 3-107: Dimensions des bacs et blocs enfichables de petit facteur de forme

La CEI 60297-3-107:2012 définit les dimensions d'interface entre des bacs et des blocs enfichables associés à l'aide de connecteurs comme cela est défini dans la spécification PICMG-MTCA.0 (cartes fixes, voir Figure 7) et dans la CEI 61076-4-116 (en deux parties, voir Figure 12) et d'autres connecteurs en deux parties (voir Figure 15). Pour les essais mécaniques et climatiques, se rapporter à la CEI 61587-1. Pour les essais de performances du blindage électromagnétique, se reporter à la CEI 61587-3.
