KM6-II HD (Heavy Duty) Subrack

The KM6-HD (Heavy Duty) subrack system, although primarily designed for military and railway use, would suit any rugged application where a high resistance to shock and vibration is required. Built to meet MIL-STD-167, its features include positive guide locking / retention, heavy two-screw fixing tiebar extrusions, 3mm thick side plates / rack angles and a conductive finish throughout.
Accuracy is maintained by the use of counter sunk holes in the side plates which ensure correct alignment of the tiebars via the M4 screw fixings. Electro Magnetic Compatibility (EMC) is assured with the use of RFI gaskets in the 19” rack mounting angles and closing angles, providing a seal to adjacent panels in the front and rear apertures. Side plates are solid whilst optional top and bottom covers may be fitted either plain or with an EMC vent pattern for cooling purposes. All metal parts are conductively finished, ensuring electrical continuity.
The KM6-HD subrack accepts standard Eurocards in 3U, 6U and 9U heights and depths of up to 400mm in both IEC60297 and IEEE1101.10/11 standards. This makes the card frames suitable for housing popular backplane types such as VMEbus, VXI, VME64 Extensions, VPX, VXS, CompactPC, PXI and also DIN connectors with the use of a connector mounting extrusion.
KM6-HD subracks are supplied in kit form as standard but can be shipped fully assembled upon request. They are compatible with the comprehensive range of KM6-II accessories including; front panels, plug-in units and peripheral mounting assemblies.
KM6-HD subracks can be ordered as kits or as individual piece parts.

Backplane Mounting Subrack Kits – IEC 60297

The below basic kits include side plates, tiebars, tapped strips, 19” rack angles, gasket and fixings – as shown in the exploded views to the right.
For Eurocard backplanes, VMEbus, VXI etc

Backplane Mounting Subrack Kits – IEEE 1101.10/11

The below basic kits include side plates, tiebars, tapped strips, 19” rack angles, gasket and fixings.
For VME64 Extensions, VPX, CompactPCI, PXI etc.

Backplate Mounting Subrack Kits – IEEE 1101.10/11 With Rear Transition Area

These kits include side plates, tiebars, tapped strips, 19” rack angles, rear closing angles, gasket and fixings. Although the IEEE specification defines a number of different card depths, by far the most common IEEE 1101.10/11 subrack configuration is a 160mm front card area and an 80mm rear transition card area and this is what is therefore offered below.
For VME64 Extensions, VPX, CompactPCI, PXI etc.
