33、7:2012 6 60297-3-107 IEC:2012 INTRODUCTION This standard provides for 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 in equipment practice are rapidly gaining acceptance. Recognizing this deve

34、lopment it became obvious that a generic interface standard would be an advantage to the industry. This 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 inter

35、face 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. In order to meet the requirements

36、 of small form factor plug-in units within the subrack the interface dimensions required differ from IEC 60297-3-101. This standard defines these small form factor interface dimensions. The small form factor generic dimensions are based on and coordinated with AMC.0 and MicroTCA. Since the AMC.0 and

37、 MicroTCA Specification defines only a limited range of connectors this standard opens the possible use of other suitable connectors.
