Tapped Strips
Tapped M2,5 holes on a pitch of 1HP, these strips are used for fixing front panels, backplanes, or as an option for chassis plates. As an alternative to tapped strips, a slide nut suitable for use in front tie bars only can be used where a small number of locations are required. Also available is an M3 tapped strip for such applications as ATCA backplane mounting.

In both cases, the kit comprises two extrusions and fixings.
Description Quantity Order Code 6HP Horizontal Extrusion Separate Kits 2 950- 84HP Horizontal Extrusion Separate Kits 2 950-Backplane Spacer Strips
Two types of spacer strips are available, insulating and conductive. The insulating type is available in one and two level versions, each having half shears to aid assembly. The two-level version is used on centre rear tie bars. The 84HP strips can be easily cut down for smaller widths. The conductive strip is 42HP wide and supplied singly.
Note: If conductive spacer strips are used in 84HP subracks please order 2 x 42HP spacer strips per tie bar.
KM6-II Guides
A number of different guides are available to suit both standard eurocards and also 111.76/245.1mm high (3U/6U) plug-in units, in a variety of depths and card thicknesses.
Single Part Guides
Type 1 PCB For Eurocards of 1,6mm thickness, either 100mm, 160mm or 220mm long. Compatible with grounding clip & bolt-down screw.
Type 2 PCB For Eurocards of 2,4mm thickness, either 160mm or 220mm long. Not compatible with grounding clip or bolt-down screw.
Type 3 PIU For standard plug-in units (111.76 or 245.1mm height), 1.6mm thickness, 160mm or 220mm long. Not compatible with grounding clip, compatible with bolt down screw.
Type 4 PCB For Eurocards of 1,6mm thickness, 220mm long, this guide will fit over intermediate extrusions, permitting mixing of pcb depths. Compatible with grounding clip & bolt-down screw.
Three Part Guides
For Eurocard PCB or PIU depths of 280mm, 340mm & 400mm, the below three part guides should be used. Comprising a centre aluminium section (with plastic insert) and two guide feet, they can easily be cut to suit other custom lengths. (Note that the centre extrusion should be cut 76mm short of the desired eurocard length, e.g. a 400mm guide would have a 324mm long extrusion).
PCB Grounding Clip
This grounding clip can be inserted into the front or rear of 1,6mm pcb guides in KM6 subracks.
Features
– Electrostatic Protection
– Occupies ‘unused’ area of Eurocard
– No screws required
Contacts on the clip provide electrical continuity between a suitably equipped Eurocard and, via a spring under the clip to standard front extrusions. Pcb’s can, therefore, be grounded before the engagement of connectors. The clip, which is supplied in packs of 10, fits into a ‘pocket’ in the guide and requires no screw fixings to maintain contact.
The modification required to the pcb takes the form of a conductive strip along the edge of the board, either on the left or right side. The clip has been tested to IEC 950: section 2.5.11. In testing, the clip reached a steady temperature of 76 degrees C at 15A, with a resistance path of 7mΩ. A typical electrostatic discharge would be 12A for a period of 1 microsecond. It should be noted that the clip is designed to provide a ground path for electrostatic charges, not for a power short circuit or as a ground rail.
Positive Guide Retention – Tapped Strips
All KM6-II guides, with the exception of the 2,4mm slot version, can be bolted down to a tapped strip in the front extrusion to give shock and vibration resistance. Tapped strips (supplied singly) should be selected by subrack width. The screw used is M2,5 x 5mm cheesehead, supplied in a packet of 100.

Card retainers are available in two types, normal and security. The normal retainer is positioned directly in front of the guide moulding and is operated by finger pressure as illustrated to release the PCB. The security retainer is designed for extra security in vibrative environments and is operated by a unique screw arrangement.
Once clipped in position in front of a PCB guide, complete security is achieved by 3 turns anti-clockwise of the retaining screw with a screw driver.
PCB Injector/Ejector
PCB’s fitted with multiple DIN connectors can require very high insertion and withdrawal forces. These injector/ejectors comprise levers which fit to the PCB and saddles which are retained in front of the guide. It is recommended that guides are screwed down where insertion forces are excessive.
Description Quantity Order Code PCB Injector/Ejector 10 Pairs 950-PCB Guide Nose
– Assists location of PCBs
– Extends existing KM6 PCB guide
The guide nose fits to standard 1,6 PCB guides, extending their length to within 5mm of the inside face of a front panel. The increased length is especially useful for locating circuit boards in subracks which are above or below eye level. It also provides a purchase point for the operation of certain types of card ejector.
KM6-II Front Divider Kits
KM6-II, front divider kits can be fitted after assembly of the subracks.
For use with 6U subracks, these divider kits provide a useful way to mix 3U and 6U board heights within a unit. The divider section is available in different widths, from 21HP to 84HP, and divides the subrack from either the left hand or right hand side.
The design of the kit is such that there is no loss of front panel space. It should be noted, however, that the divider plate restricts the use of ‘C’ type connectors to plug-in units of 4 HP width, or greater, at the position immediately to the left of the plate.
9U Front Divider Plate
This plate will divide a 9U subrack into 3U and 6U sections. It should be ordered in conjunction with 6U front divider kits. (The 6U plate is discarded.)

Rear Divider Kits
Rear dividers shorten the depth of the subrack by 60mm locally at the rear, and are employed when it is necessary to use mixed depth PCBs or modules within a 3U or 6U subrack. Example: where 160mm PCBs are required in a frame where the rear extrusions are set for 220mm deep PCBs. Rear dividers can be supplied as listed below (as a 6U kit), or can be configured by using 3U and 6U dividers together with rear tie bars and tapped strips which are available separately.
Rear Divider Plates
Description Quantity Order Code 3U Divider Plate 1 950- 6U Divider Plate 1 950-Non Standard Width Rear Divider Extrusion
In order to produce other widths of divider kits, a larger, standard width should be modified as shown. Please note that the tie bar lengths differ depending upon whether the required divider area is left or right handed.
Cover Kits
Top and Base Cover kits
This range of top and base covers are suitable for fitting to both Standard and Universal KM6-II subracks . Two depths are available for protecting the guide area of 160mm or 220mm boards. The covers are available in ventilated or unventilated versions and can be fitted after the subrack has been assembled. A slot in the rear tie bar captures the cover and plastic clips secure it to the front. The cover can thus be easily removed for access.

Suitable for both Standard and Universal KM6-II Subracks, these are available in heights of 3U and 6U and are assembled to the endplates. All KM6-II endplates are pre-punched to accept these covers. The rear cover adds 41mm to the overall depth of a subrack.
Horizontal Mounting Modules
This unit, which fits into a subrack like a 3U module, is actually a 6U x 20HP subrack on its side. This module permits the use of normal guides, front panels, plug-in units etc. and solves the problem of housing double Eurocards, i.e. 6U cards, in a 3U subrack, a situation which is frequently associated with modern bus systems.
The horizontal mounting module offers a number of additional advantages. It can be sub-assembled separately from the main subrack, and it offers “chimney” cooling between the end plates.
Peripheral Mounting Adapters (PMA) & Air Baffle Cards
Peripheral Mounting Adapters (PMA)
Verotec’s peripheral mounting assemblies (PMAs) are designed to comply with industry standard IEC (for standard eurocard applications) and IEEE.10, for use in VME64 Extensions and CompactPCI systems. Standard eurocard types use a 3mm anodised aluminium front panel with fixed handles whilst VME64x & CPCI types have chromated (conductive) front panels with RFI gasket and fixed handles. Both are supplied with fixing hardware.
Three types are available; the first is for vertically mounting a single standard 5.25”, front accessible peripheral such as a CD / DVD drive. The second is for mounting one standard 3.5”, front accessible peripheral (such as a floppy disk) and one standard 3.5”, embedded peripheral (such as a hard disk drive). The third is for mounting a single 2.5” embedded hard disk drive.
