BS EN 60297-3-108:2015

What is BS EN 60297-3-108 - Dimensions of R-type 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 60297-3-108 provides dimensions and features for R-type sub-racks and plug-in units, i.e. ruggedized variants of the mechanical structures of the 482,6 mm (19 in) series, with enhanced vibration and shock resistance and/or improved EMC performance, for use in more harsh environment.  

BS EN 60297-3-108 contains a sub-rack standard that is externally compatible with IEC 60297-3-100 but internally largely incompatible with IEC 60297-3-101. R-type sub-racks, chassis integrated sub-racks and plug-in units incorporate dimensions and features that provide for a higher level of ruggedness, compared with IEC 60297-3-101 (test set-up and load definitions are selected from IEC 61587-1 and IEC 61587-5). 

Who is BS EN 60297-3-108 - Dimensions of R-type sub-racks and plug-in units for?  

BS EN 60297-3-108 on the dimensions of R-type sub-racks and plug-in units is useful for:  

• Manufacturers of electronic devices  
• Manufacturers of telecommunication equipment 
• Maintenance and augmentation teams   
• Companies associated with designing and installation of electronic devices  
• Fault management teams 
• Quality management teams 

Why should you use BS EN 60297-3-108 - Dimensions of R-type sub-racks and plug-in units? 

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. There are certain specifications regarding the performance of electronic equipment. 

BS EN 60297-3-108 establishes alternative dimensions and features for sub-racks and associated plug-in units, compared with IEC 60297-3-101. These alternatives allow more sturdy designs for the load-bearing members of the sub-rack. In addition, the plug-in units are with alignment pins and fastened with M3 screws. Chassis integrated sub-racks are also part of BS EN 60297-3-108. 

BS EN 60297-3-108 discusses RA–type sub-rack, RB–type sub-rack, R–type sub-rack guide rails, electromagnetic shielding provisions and mounting flanges, chassis integrated sub-rack, front panel/plug-in unit compatible with RA–type sub-rack, front panel/plug-in unit compatible with RB – type sub-rack, injector/extractor handle, printed board dimensions that help you perceive the standard dimensions of R-type sub-racks and plug-in units for further industrial uses. 

The guidelines in BS EN 60297-3-108 enables you to provide a superior quality product to end-users.
