Amphenol LMD-LMS Modular Connectors
NO NEED FOR EXPENSIVE PC BOARDS AND HARDWARE
LMD/LMS Modular Connectors were designed by Amphenol Pyle-National to provide flexibility in the assembly of wire harnesses that are used in instrumentation and avionic control environments. The design of the LMD Modular Connectors provides a rack and panel or cable to cable attachment. LMS Modular Connectors allow an in-line splice using the same modules.

CONTACTSAMPHENOL LMD-LMS MODULAR CONNECTORS - CRIMPING, INSERTION, & REMOVAL OF CONTACTS
Amphenol recommends the tools listed on the Contacts & Tooling Section for use with LMD connectors, and also the following procedures for wire preparation, crimping of wire and contact insertion and removal. Wire Preparation 
Strip wires to dimension “A” shown in table. Avoid cutting or nicking wire strands. Contact Size Wire Size Sealing Range Stripping Length Dimension "A" 22 20, 24, 26, 28 AWG 0.054 (1.37) 0.156-0.125 20 20, 22, 24 AWG 0.083 (2.11) 0.185-0.155 16 16, 18, 20 AWG 0.103 (2.61) 0.260-0.230 8 8, 10 AWG 0.255 (6.48) 0.395-0.35 Crimping Wire to Contacts
STEP 1: Fully insert wire into contact crimp pocket. Wire must be visible through wire inspection hole. STEP 2: Insert contact into tool (use proper crimping tool as listed in Contacts & Tooling). Crimp contact to wire. Tool will not open if contact is not fully crimped. STEP 3: After crimping, wire should be visible through wire inspection hole. Contact Insertion
STEP 1: 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. STEP 2: 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. Contact Removal
MODULE & STRAIN RELIEFAMPHENOL LMD-LMS MODULE CONNECTOR - MODULE INSERTION/REMOVAL & USE OF STRAIN RELIEF
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 103 & 104, or select the optional bussing, diode or relay modules offered, shown on pages 105 & 106. The next instructions illustrate the proper method of insertion and removal of modules within the LMD connector. Module Insertion
Module Removal
STEP 1: 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. STEP 2:With the module removal tool fully inserted, push the extraction plunger to eject the module out of the rear of the connector. 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-5300-10A (see page 107).
Tape wire bundle in area of cable clamp, and build up diameter to approx. 3/8 inches, if required. 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. Opening Strain Relief to Service Modules and Contacts
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. 45° 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 45° each, then remove module, then remove strain relief. |
