REQUIREMENTS 3.1. Storage A. Ultraviolet Light Prolonged exposure to ultraviolet light may deteriorate the chemical composition used in the header assemblies or housings. B. Shelf Life The header assemblies and housings should remain in the shipping containers until ready for use to prevent damage. These products should be used on a first in, first out basis to avoid storage contamination. 2 of 16 Rev F 114- 19048 C. Reeled Contacts When using reeled contacts, store coil wound reels horizontally and traverse wound reels vertically. D. Chemical Exposure Do not store housings or header assemblies near any chemicals listed below, as they may cause stress corrosion cracking in the components. Alkalies Amines Ammonia Carbonates Citrates Nitrites Phosphates Citrates Sulfur Nitrites Sulfur Compounds Tartrates Where the above environmental conditions exist, phosphor--bronze contacts are recommended instead of brass if available. NOTE i 3.2. Special Characteristics AMP--DUAC Connectors are available as a wire--to--board or wire--to--wire connector system designed for power applications. The housings and header assemblies are designed on 4.2 x 4.2 mm centerlines. The housings are polarized to prevent miss--mating. The vertical headers are available with or without mounting pegs and drain holes. 3.3. Wire Selection and Preparation The contacts will accept a wire size range of 26--22 and 22--18 AWG, and are to be terminated to stranded wire. Figure 2 lists the insulation diameter range, strip length, and crimp height as determined by the wire size. CAUTION ! NOTE i When stripping the wire, care must be taken to avoid scraping, nicking, or cutting the conductor. Care must also be used when handling the wire during stripping and crimping to prevent cracking or breaking of the conductor and insulation. Each crimp dimension represents the functional range of a wire/contact combination. There are tool designs available to meet various application requirements. The developed crimp configuration is unique for each tool design and is acceptable provided the crimp height is within the functional range. For crimp dimensions of a specific tool, refer to instruction sheet packaged with manual tools and applicator log packaged with power tools.

Crimped Contact Requirements The contact shall be located in desired tooling and crimped according to the instructions packaged with that tooling, if available. See Section 5, TOOLING, of this document for details on tooling options and instructional materials. CAUTION ! Wire insulation shall NOT be cut or broken during the crimping operation, nor shall the insulation be crimped into the contact wire barrel. Reasonable care should be taken by tooling operators to provide undamaged wire terminations. A. Contact Crimp Features Figure 3 shows a typical contact as it should appear after crimping. 1. Crimp Location For optimum crimp effectiveness, the crimp must be within the area shown and must meet the crimp requirements provided in Figure 3. 2. Crimp Height The crimp applied to the wire barrel portion of the contact is the most compressed area and is most critical in ensuring optimum electrical and mechanical performance of the terminated contact. The contact wire barrel crimp height must be within the dimension provided in Figure 2. 3. Effective Crimp Length Effective crimp length shall be defined as that portion of the wire barrel, excluding bellmouth(s), fully formed by the crimping tool. See Figure 3. 4. Conductor Extension The conductor may extend beyond the wire barrel to the maximum shown in Figure 3. 5. Wire Barrel Seam The wire barrel seam must be closed with no evidence of loose wire strands visible in the seam. 6. Conductor/Insulation The conductor and insulation must both be visible in the area between the insulation barrel and the wire barrel. 7. Bellmouth The front and rear bellmouths are caused by the extrusion of metal during crimping and must be within the range specified in Figure 3. 8. Cutoff Tab and Burr The cutoff tab and burr resulting from the contact being cut from the carrier strip must be within limits to allow the contact to be fully inserted and seated in the housing. See Figure 3. 9. Flash The wire barrel flash at the bottom of the wire barrel results from applied crimp pressure and must be within the dimension provided in Section X--X of Figure 3. 4 of 16 Rev F 114- 19048 NOTE: Receptacle contact shown, but pin contact dimensions are the same.

Twist and Roll There shall be no twist, roll, deformation, or other damage to the mating portion of the crimped contact that will prevent proper mating. See Figure 4. No Twist Permitted Wire Barrel Front of Contact Figure 4 Rev F 5 of 16 114- 19048 C. Straightness The force applied during crimping may cause some bending between the crimped wire barrel and the mating portion of the contact. Such deformation is acceptable within the following limits. 1. Up and Down The crimped contact, including cutoff tab and burr, shall not be bent above or below the datum line more than the amount shown in Figure 5. 2. Side to Side The side--to--side bending of the contact may not exceed the limits provided in Figure 5. NOTE Periodic inspections must be made to ensure crimped contact formation is consistent as referenced. i Wire Up and Down Bending 3_ Max 3_ Max Datum Line Wire Side--to--Side Bending 3_ Max Datum Line 3_ Max Figure 5 3.5. Placement of Crimped Contact in Housing The contact must be inserted in the back of the housing and snapped into place. For the plug housings, install the contact so the wire barrel is facing the housing latch. For the receptacles, orientation of the contact can be in either direction. When fully inserted, the locking lances will engage the housing and prevent backing out during mating of the connector. After inserting contact into housing, pull back lightly on the wire to ensure contact is fully seated. See Figure 6. Contacts Fully Inserted in Plug Housing Pin Contact Locking Lance Back of Plug Housing Figure 6 6 of 16 Rev F 114- 19048 3.6. Strain Relief and Wire Dress If required, wires can be bundled together and supported with cable ties. Wires must not be stretched or confined in any way that would restrict the floating action of the contacts. Therefore, the wires must remain perpendicular to the connector and avoid an excessively sharp bend radius. The minimum distance for the cable tie, measured from the wire end of the connector to the cable tie is shown in Figure 7. Also, refer to Instruction Sheet 408--8330 for information on assembly of the strain relief for the 6--position AMP--DUAC Connector. 76.2 Min Distance Cable Tie Wires Figure 7 3.7. Connector Assembly The plug and receptacle connectors will mate according to the polarization designed in the housings. Once the connectors have been mated, the latch will secure them from becoming unmated. See Figure 8. Plug and Receptacle Connector Must be Locked Together Plug Connector Receptacle Connector Figure 8 3.8. Wire Bend Radius TE Engineering recommends that individual cables should be dressed to a bend radius of at least ten times the cable outside diameter. Likewise, cable bundles should be dressed to a bend radius of at least ten times the diameter of the bundle. 3.9. Panel Cutout AMP--DUAC Connector panel cutouts shall be as indicated in Figure 9. No mounting hardware is required. The plug housing features flexible mounting tabs for insertion into the panel. Push the plug connector through the panel -- in the same direction as the cutout was made -- until it snaps in place.

PC Board Header Assembly Placement CAUTION ! The header assemblies should be handled only by the housing to prevent deformation or other damage to the solder tines. A. Manual Placement Align the header assembly solder tines with the appropriate holes in the pc board. Start all solder tines into the board, then press on the header until it seats on the pc board. B. Robotic Placement The robotic equipment must be adjusted to feed, pick up, and place the headers on the pc board with an accuracy of 0.25. The header assembly datum surfaces detailed on the customer drawing will ensure correct placement of the header. For information on robotic equipment, see Section 5, TOOLING. 3.14. Soldering A. Flux Selection Contact solder tines must be fluxed prior to soldering with a mildly active, rosin base flux. Selection of the flux will depend on the type of pc board and other components mounted on the board. Additionally, the flux must be compatible with the wave solder line, manufacturing, health, and safety requirements. Call the Product Information phone number at the bottom of page 1 for consideration of other types of flux. Some fluxes that are compatible with these header assemblies are provided in Figure 12.

Vertical Header Assembly Vertical or Right-- Angle Header Assemblies Must be Flush Against PC Board to 0.08 Max 1.78 Thick PC Board PC Board Solder Tine Figure 16 3.16. Polarization The configuration of the AMP--DUAC Connector mating cavities prevents accidental inversion when mating the two components. 12 of 16 Rev F 114- 19048 3.17. Mating of Connectors To ensure a proper circuit connection, the receptacle connector latch must fully engage the header assembly locking ramp. 3.18. Header Assembly Spacing Care must be used to avoid interference between adjacent header assemblies and/or other components. If robotic equipment is used, space allowances will be required for the grippers. 3.19. Repair/Removal Use an extraction tool to remove individual contacts from connectors for replacement or for relocation to another housing cavity. Extraction Tool 188688--1 is used to extract contacts from receptacle connectors. See Figure 17. Reset the locking lances to the original spread before reusing contacts. Damaged or worn contacts may be replaced provided there is sufficient slack, after restripping the wire, to insert the new contact into the connector. Refer to Section 5, TOOLING. Damaged pc board header assemblies may be removed from the pc board by standard de--soldering methods.

NOTE i TE Tool Engineers have designed machines for a variety of application requirements. For assistance in setting up prototype and production line equipment, contact Tool Engineering through your local TE Representative or call the Tooling Assistance Center number at the bottom of page 1. S Hand Crimping Tools Hand crimping tools that accommodate the full wire size range are designed for prototype and low--volume applications such as repair of damaged contacts. S Applicators Applicators are designed for the full wire size range of strip--fed, precision formed contacts, and provide for high volume, heavy duty production requirements. The applicators can be used in bench or floor model power units. Rev F 13 of 16 114- 19048 NOTE i Each applicator is shipped with a metal identification tag attached. DO NOT remove this tag or disregard the information on it. Also, a packet of associated paperwork is included in each applicator shipment. This information should be read before using the applicator; then it should be stored in a clean, dry area near the applicator for future reference. Some changes may have to be made to the applicators to run in all related power units. Contact the Tooling Assistance Center number at the bottom of page 1 for specific changes. S Power Units A power unit is an automatic or semi--automatic device used to assist in the application of a product. Power unit includes the power source used to supply the force or power to an applicator. NOTE i The Model “K” AMP--O--LECTRIC Terminating Machine PN 565435--5 (409--5128) has been superseded by the Model “G” Terminating Machine PN 354500--1 (409--5842) for new applications. For existing applications, the Model “K” is still recommended because of the large number of installed machines. S Robotic Equipment Robotic equipment for placement of the header assemblies on a pc board must have a true position accuracy of 0.25 to ensure proper location and insertion of the solder tines. This includes gripper and fixture tolerances as well as equipment repeatability. It must use the assembly datum surface to ensure reliable header placement. If you need assistance in setting up prototype or production line equipment, contact Tooling Engineering through your local TE Representative or call the Tooling Assistance Center number at the bottom of page 1. S PC Board Support A pc board support must be used to prevent bowing of the pc board during insertion of the headers. It should have a flat surface with holes or a channel large enough to receive the solder tines during installation. S Extraction Tools Extraction Tools are designed to release the contacts inside the receptacle connector without damaging the housing or contacts. Refer to Paragraph 3.19.
