New technologies requiring smaller plug-in unit form factors used in 19 in equipment practice
are rapidly gaining acceptance. The IEC 60297 series of standards provides definitions of mechanical structure and dimensions for 19 in cabinets and racks and their compatible subracks and chassis. The combination of 19 in based cabinets or racks and subracks and chassis is broadly applied to all industrial electronic fields in the world.
BS EN 60297-3-107 provides for an alternative/smaller form factor of plug-in units as defined in IEC 60297-3-101. BS EN 60297-3-107 defines the interface dimensions between subracks and associated plug-in units using connectors as defined in PICMG-MTCA.0 and IEC 61076-4-116 and other two-part connectors. For mechanical and climatic tests refer to IEC 61587-1. For electromagnetic shielding, performance tests refer to IEC 61587-3.
In order to meet the requirements of small form factor plug-in units within the subrack the interface dimensions required differ from IEC 60297-3-101. BS EN 60297-3-107 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 MicroTCA Specification defines only a limited range of connectors BS EN 60297-3-107 opens the possible use of other suitable connectors.
BS EN BS EN 60297-3-107 on the dimensions of subracks and plug-in units is useful for:
Electronic equipment is used in applications that rely on mechanical or electric systems for their operation. They are essential to any work on electronics systems for creating signals and capturing responses from electronic devices. Sub-racks are used for the reception of printed circuit boards and plug-in units in industries like telecom, test and measurement, transportation, aerospace etc. There are certain standardized specifications contributing to the performance of subracks.
The technology in BS EN 60297-3-107 is helpful for increasing the overall market acceptance, and availability and also reducing the cost by making critical interface dimensions available and permitting the use of alternative connectors to the industry (beyond AMC.0 and MicroTCA). BS EN 60297-3-107 discusses an arrangement overview that depicts a user-friendly idea of subracks and plug-in units. BS EN 60297-3-107 also provides users with dimensions of subracks, plug-in units, printed boards related to connectors and backplanes which contributes to the performance characteristics of subracks and plug-in units ensuring their reliability. The guidelines in BS EN 60297-3-107 help you perceive the dimensions of subracks and plug-in units that enable you to provide a superior quality product to your customers.
