What is BS EN 60297-3-104 - Dimensions of sub-racks and plug-in units about? 
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. BS EN 60297-3-104 covers the connector dependent interface dimensions for subracks and plug-in units in accordance with subracks of IEC 60297-3-101. BS EN 60297-3-104 deals with the two-part connectors of the series IEC 60603-2, IEC 61076-4-101 and IEC 61076-4-113.
Since the connector specific standards contain the dimensions of the connectors only, BS EN 60297-3-104 introduces the related sub-rack and plug-in unit interface dimensions if the connectors mentioned are applied. BS EN 60297-3-104 will also provide dimensional guidelines for the implementation of other connectors by definition of the relationship between sub-rack mounting pitches and the position of board-type plug-in units and backplanes.
