Rear panel mount panel thickness range .062 Max.(Std, except for ***), .062-.093 (metric). Por front panel mount applications, it is recommended that cable assembly be fed from the front cf the panel to avoid excessive bending of the cable which would occur if fed from the rear of the panel. Loose piece shielded (EMI) product can be Front or rear panel mounted, while the pre-assembled shielded (EMI) product can only be rear panel nounted. ** = Screw lock version only. aek)6Panel thickness may be .093 Maximum for bail lock applications with 4-40 screws, but clearance between the incoming wating connector and bail clips on pre-assembled parts is minimal. + For Metric application of pre-assembled product use rear panel mount dimension given for IEEE-488 Metric in Table.

Additional Strain Relief Requirements If the terminated connectors (cable-to-cable) are going to be used in an area where an extreme amount of axial pull or 90 pull will be present, the addition of strain relief 554099-1 is recommended, see Figure 3. At present only the 50-position strain reltef is available, but other positions can be produced if required. 90 CABLE PULL. / . = . PULL LD srrain STRAIN RELIEF 554099-1 Fig. 3 Strain Relief 4.3. Special Cable Preparation Requirements A. Cable Types These connectors are designed to terminate ribbon cable with solid or stranded round conductors on .050-in. centerlines.

Cable Insulation The connector has been tested and found to be compatible with a wide variety of cable insulations including: extruded, coextruded, single laminated, and double laminated. However, due to the many variations in cable construction and insulating material hardness, it is recommended that sample terminations be made on the proposed cable to assure compatibility with the connector. If problems are encountered, please forward a cable sample to AMP Product Engineering for further evaluation. C. Cable Storage Proper storage of the cable is important to prevent distortion of the centerline dimension which could cause terminal registration problems. The cable should be stored with the "flat" side supported. Reels must be stored in an upright position (standing on edge), or they must be supported on an axle, D. Cable Preparation The cable should be cut straight and perpendicular to the conductors. Do NOT tear or cut the cable with scissors, razor blades, or paper cutters which can pull strands of wire across the cut face of the cable and cause shorts. Use AMP Cable Cutter 91220-1 and refer to IS 6574 for proper procedures. See Figure 5 Fig. 5 Cable Cutter AMP | AMP INCORPORATED PAGE 3 NO.

Cover Glosure To verify that the connectors have been fully terminated, make sure the strain relief latches are securely fastened and there is no gap between the housing assembly and cover.
