Guide Rails

Guide rails form the interface between the subrack mechanics and the sub-assemblies (PCB boards, plug-in units, frame-type plug-in units, ...).


Guide rails for standard applications are 2 HP wide. Guide rails with coding (e.g. for CompactPCI or VME64bus applications) are 4 HP wide.


There are groove widths of 2 mm and 2.5 mm.


The guide rails are clipped into the rectangular cut-outs of the horizontal rails. They can additionally be bolted to the horizontal rail (type Heavy only) for higher shock and vibration requirements (Torque max. 0.2 Nm).


The printed HP markings on the horizontal rail allow the rails to be fitted in the correct position easily (position of sub-assembly = "number in viewing window" or in front of the arrow marking on the guide rails).
