KM6-HD Subracks – Value Added Services from Verotec… CUSTOM KM6-HD SUBRACKS TecServ+ is the vehicle by which Verotec delivers its value added services. These fall within 5 main categories and are described below. When it comes to KM6-HD subracks, we’ve worked with many customers in the past to design, manufacture and help bring to market modified and custom versions of our standard products – a small selection of these are pictured below. If you have any special KM6-HD subrack requirements, please contact our sales office ENGINEERING SERVICES: Complete review of commercial,...

KM6-HD (Heavy Duty) Subracks - Introduction 1 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...

KM6-HD (Heavy Duty) Subracks: Rear Plug-Up Versions BACKPLANE MOUNTING SUBRACK KITS – IEEE 1101.10/11 WITH REAR TRANSITION AREA (For VME64 Extensions, VPX, CompactPCI, PXI etc.) These kits include side plates, tiebars, tapped strips, 19” rack angles, rear closing angles, gasket and fixings – see exploded view right. 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. ORDERING INFORMATION – WITH REAR...

KM6-HD (Heavy Duty) Subracks: PiECE part SIDE PLATES KM6-HD side plates are manufactured from 3mm thick aluminium for additional strength and rigidity. Tiebar fixing positions are punched on the Eurocard pitch of 60mm along the length of the side plates, allowing various subrack configurations to be assembled. Countersunk holes are used to ensure accurate alignment of tiebar extrusions and a conductive finish is applied throughout. * 160+80 depth side plates are designed for rear plug-up applications and meet the requirements of IEEE 1101.10/11. These provide for a 160mm front card area and...

KM6-HD (Heavy Duty) Subracks: Piece parts CLOSING ANGLES CLOSING ANGLES KM6-HD closing angles are normally fitted to the rear of a subrack to interface with a rear panel or IEEE 1101.10/11 panels / modules in rear plug-up applications. They can also be positioned at the front if 19” rack angles are not fitted. The extrusions accept a slide-on metal gasket (not included) which forms an EMC tight seal between it and the adjacent front / rear panel in a subrack. IEEE 1101.10 geometry 3U, 6U & 9U Accepts slide-on, EMC gasket (not supplied) Conductive finish Material / Finish Closing Angle...

KM6-HD (Heavy Duty) Subracks: Piece parts FRONT TtEBARS KM6-HD front tiebars feature a heavy, extruded profile and twin screw fixing method to ensure strength and rigidity in demanding applications. Provision is made for card guides to be placed at 1HP (5.08mm) increments and positively retained with 2 screws, increasing their resistance to shock and vibration. For EMC applications, a slot is included in the extrusion for covers to be located without the need for additional seals. IEEE 1101.10 versions have an extended front lip with rectangular cut outs to aid compliant Injector /...

KM6-HD (Heavy Duty) Subracks: Piece parts & Accessories CENTRE REAR TIEBARS When fitted with tapped strips these tiebars are used as centre rear backplane supports / mountings. In order to maintain correct connector geometry it is necessary to fit a spacer, either conductive or insulating between extrusion and backplane. Rear backplane tie bars can be converted to DIN 41612 connector mounting tiebars by means of a connector mounting adaptor – see below. Heavy profile for extra rigidity 42HP & 84HP widths Two screw fixing design for added strength Conductive finish CENTRE REAR TIEBAR...

KM6-HD (Heavy Duty) Subracks: Accessories CARD GUIDES SINGLE PART GUIDES KM6-HD card guides serve to support, guide, earth and code PCBs in a subrack. They are easily snapped into place between the front and mid/rear tiebar extrusions but can also be screwed front and back to improve resistance to shock and vibration. Screws should be ordered separately as should grounding clips, ESD springs and coding keys. The range of guides available can cater for board depths of up to 400mm in both 1.6mm & 2.4mm thicknesses. The underside of the guide has been designed to be aerodynamic so as to aid...
