Precision tooling permits ali contacts to simultaneously penetrate the cable and engage the conductors without prestripping the insulation. A cover is latched onto the assembly to provide contact protection and cable strain relief. It is fluted for cable orientation, with plastic barbs for cable alignment. The locking latches and barbs hold the cover on. This instruction sheet covers connector selection, cable requirements, accessories, and termination tooling for the CHAMP Latch Low-Profile connectors listed in Figure 1. Read this material, and those referenced, befare assembling any connectors. All dimensions presented on this instruction NOTE : sheet are in inches, unless otherwise stated. 2. DESCRIPTION Plug (male) and receptacle (female) connectors consist of polarized housings which are preloaded with contacts on .085-in. centers. The terminating ends of the contacts are on .100-in. centers for an * Trademark of AMP Incorporated effective .050-in. staggered termination. CHAMP Latch connectors may be used in dead end (flush) or daisy chain (feed thru) applications. 3. TERMINATION TOOLING There are two terminating tools, each designed for a specific purpose. Hand tool 231561-1 (see Figure 2) is designed for field termination or low volume plant termination of connectors. The toot may be used for dead end or daisy chain applications. Refer to AMP Instruction RETRACTABLE CABLE STOP Sra < Fa a oe Of HAND TOOL 231561-1 BENCH MOUNT KIT 231552-1 Fig. 2 PAGE 1 OF 5IS 3158 Sheet IS 3135, packaged with the hand tool, for complete operating procedures. Bench Mount Kit 237552-1 is available for supporting the hand tool. Tooling Assembly 231576-1 (see Figure 3) is designed for production rate plant operation. The tool may be used for dead end or daisy chain appli- cations. The tooling assembly is designed for use in the AMP Manual Arbor Frame Assembly 91085-2. Refer to AMP Instruction Sheet iS 3134, packaged with the tooling assembly, and 1S 7777, packaged with the frame assembly, for complete operating procedures.

Check to be sure there is no gap between the housing assembly and cover. Make sure the strain relief latches are securely fastened (see Figure 5). Fig. 3 4. CABLE REQUIREMENTS The hand tool and tooling assembly will terminate ribbon cable with No. 26 AWG solid conductors, No. 28 AWG solid or stranded conductors, or No. 30 AWG solid conductors to 14-, 24-, 36-, and 50-position low-profile connectors. Refer to Figure 4 for recommended cable dimensions. CAUTION] [fe cable end must be cut 90 to the edge of fhe cable; atherwise an improper termi- nation will result, AMP Ribbon Cable Cutting Hand Tool 31220-1 is recommended. Refer to instruction Sheet |S 6574, packaged with the tool, for propr use. Laminaied cables are manufactured to various specifications. Aili cables are NOT compatible with CHAMP Latch Low-Profile connectors. Before making production assemblies, itis suggested that samples of cable be submitied to AMP Engineering for evaluation.

Select the appropriate U-shaped locking latch according to the connector size and simply slide the latch onto guide tracks until tabs snap into slots on plug connecter. As connectors are mated, tabs engage with lead-in ramps and spring over locking shoulder into receptacle siots (audible click). To release, push the latch jorward to free tabs from slots. i NO.
