Sub-rack is rugged for rail and military environments

Designed for use in rail, military, aerospace and other harsh operating environments where electronic equipment will be subject to shock and vibration during use, the ruggedised KM6-HD subrack system by Verotec is designed to meet MIL-STD 167, the US Department of Defence Test Method Standard.

The latest KM6 sub-rack family is available in 3U, 6U and 9U heights, depths of 160mm, 220mm and 400mm and in 42HP half and 84HP full widths as standard. The IEEE 1101.10/11-compliant sub-rack has positive guide locking and retention. There are also heavy-duty front and rear tie-bar extrusions with two screw fixing that give precision location and resistance to bowing or twisting, 3mm thick side plates and rack mounting angles and an Iridite NCP conductive finish throughout.

Another feature is slide-in double swipe EMC continuity gaskets fitted to the 19-inch rack mounting angles and rear closing angles providing electrical continuity to adjacent panels or modules mounted in the front and rear. The side plates are solid, and either solid top and bottom covers or EMC ventilated pattern covers that facilitate cooling will preserve EMC integrity and are available as standard. Front and rear closing panels provide a fully screened EMC environment, inject/eject front panel handles, grounding clips, ESD clips and coding keys are available. The card guides can be screwed to the tie-bars at the front and rear to improve retention.

The KM6-HD sub-rack meets the requirements of VMEbus, VXI, VME64x, VPX, VXS, cPCI, PXI and similar open architecture specifications. It accepts standard Eurocards in 3U, 6U and 9U heights with depths of up to 400mm. The sub-rack is compatible with the full range of KM6-II accessories including front panels, plug-in units and modules. Optional heavy-duty handles for the rack mounting angles are available.
