SMA Straight Connectors, Crimp Type for Braided Cable — Captive Contact

1. Slide ferrule and heat shrinkable tubing on to cable.

2. Trim cable to dimensions as shown

ABC

15,00 (.590)

9,00 (.354)

3,00 (.118)

3. Slide body over cable dielectric and under the braid until the braid is flush against the rear of the

hexagonal nut.

NOTE: When using cables with inflexible jackets, it is permissible to make two 3,17 (.125)

longitudinal slits in the outer jacket.

4. Slide ferrule flush against the body and crimp in position using ITT Cannon Crimp Tool and

suitable die set (see table).

5. Trim back dielectric and center conductor to dimensions shown.

6. Tin center conductor (DO NOT OVER TIN).

7. Assemble insulator over center conductor with counterbore in direction shown.

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

in rear of contact.

9. Assemble contact on center conductor, heat to make solder connection ensuring shoulder of

contact is flush against rear insulator. Do not allow solder to protrude outside spill hole.

10. Insert crimped assembly into back end of body and tighten to a torque of 0.70 - 0.80 Nm (100 -

110 in. ozs.).

11. Slide heat shrinkable tubing over ferrule and apply heat until tubing shrinks down.
