LMD Assembly Instructions CRIMPING, INSERTION & REMOVAL OF CONTACTS Amphenol recommends the tools listed on the preceding page for use with LMD connectors, and also the following procedures for wire preparation, crimping of wire and contact insertion and removal. LRM (Line Replaceable s) Staggered/ GEN-X Hybrids - Fiber Optics/ /RF/Power Options/ Accessories VMEx / VITA 0, Wire Preparation A Strip wires to dimension A shown in table at right. Avoid cutting or nicking wire strands. Crimping Wire to s Follow steps - for proper contact crimping. Wire Max. O. D. Insulation Stripping Length Dimension A 0--- AWG.0.. 0 0-- AWG.0.. --0 AWG.0.0.0 (with # crimp) - AWG... -0 AWG... Low Mating Force MIL-DTL-0 Hybrids - Signal/Power/ Coax/Fiber Optics HSB HDB Docking Conn./ Accessories/Install.. Fully insert wire into contact crimp pocket. Wire must be visible through wire inspection hole.. Insert contact into tool (use proper crimping tool as listed on preceding page). Crimp contact to wire. Tool will not open if contact is not fully crimped.. After crimping, wire should be visible through wire inspection hole. Insertion Removal Using proper insertion/removal tool as listed on previous page, slip wire into insertion end (colored end), placing crimp end of contact inside the slotted portion and contact shoulder against end of tool. Align contact with the cavity at the rear face of the module. Carefully push the contact into the full depth of the cavity. Withdraw tool. A slight axial pull on the wire will confirm contact is locked in proper position. Snap the extraction end (white end) of the tool over the wire of the contact selected for removal. Carefully push the tool into the full depth of the contact cavity releasing the contact retaining collet. Hold the wire against the serrations on the tool, and withdraw the tool and the wired contact from the module. 0 Amphenol for more information at 00--0 www.amphenol-aerospace.com

LMD Assembly Instructions MODULE INSERTION/REMOVAL & USE OF STRAIN RELIEF Amphenol Pin or socket modules, wired or unwired, can be inserted or intermixed in plug or receptacle housings. Select from standard module configurations shown on pages 0 & 0, or select the optional bussing, diode or relay modules offered, shown on pages 0 & 0. The next instructions illustrate the proper method of insertion and removal of modules within the LMD connector. Insertion Align the module with the proper cavity at the rear of the housing. The module keyway must be positioned to accept key in housing cavity. Carefully insert the module straight in to the cavity until fully seated and locked in place. A slight axial push on the front of the module or a pull on the cable bundle will confirm module is locked in proper position. Select module to be removed and place the blades of removal tool into the removal slots at the front of the connector. Push the removal tool into the full depth of the cavity, releasing the module retention tines. Assembly of Internal Strain Relief Strain reliefs, if required, may be assembled to plug or receptacle connectors which have a full complement of modules installed. The following is instruction for assembling the internal attachment strain relief, part number LMD-00-0A (see page 0). Removal With the module removal tool fully inserted, push the extraction plunger to eject the module out of the rear of the connector. Opening Strain Relief to Service s and s Internal attachment strain reliefs may be opened to provide module and/or contact accessibility. To service connectors, first cut and discard tie-strap on strain relief. Open strain relief halves approx. each by bending along integral flexible hinge. After servicing, close strain relief halves and install and tighten new tie-strap. To completely remove strain relief from the housing in order to provide module access; first remove tie-strap, open strain relief halves each, then remove module, then remove strain relief.

Align self-locking tines of the strain relief housing with the cavities adjacent to each module. Push the strain relief housing into place until the self-locking tines snap and lock strain relief into position. Assemble opposite half of strain relief housing to connector and tighten tie-strap to provide clamping force on the wire bundle. Amphenol for more information at 00--0 www.amphenol-aerospace.com 0
