3. Slide rear body over dielectric and under the braid until braid is flush with flange.

N.B. When using cable with inflexible jackets it is permissible to make two 3,00 (.118) long

longitudinal slits in the outer jacket.

4. Slide ferrule over exposed braid up to hex. flange.

5. Crimp using ITT Cannon Crimp Tool and suitable die set (see table). Ensure ferrule is held close to

hex. flange.

6. Slide heat shrinkable tubing over crimp and heat shrink into place using hot air gun. Air

temperature should be approximately 125

°C.

7. Trim dielectric flush with surface ‘A’ on body using a sharp knife. Take care not to nick center

conductor.

8. Trim center conductor as shown.

9. Tin center conductor (do not allow solder to touch end of body or dielectric).

10. Place a small solder preform made from 0,26 - 0,31 (.010 - .012) dia. (28 swg) multi-core solder

in rear of contact.

11. Place rear insulator over center conductor. When insulator has counterbore, the contact fits into

the counterbore.

12. Assemble contact onto center conductor, heat to make solder connection. Do not allow solder to

protrude outside spill hole.

13. Solder should be visible at inspection hole, if excess solder runs from inspection hole, remove

with sharp blade taking care not to damage plating.

14. Screw on the front body and tighten to a torque of 0.14 Nm (20 in. ozs.).

Only common cable retention features are shown in detail - various body configurations can
