Shielded Cable Preparation

NOTE

Solder sleeves with pre-installed shield drains can be used instead of separate shield terminators (12)
and individual wires (13). A preferred solder sleeve is M83519/2-X series with a pre-installed shield
drain.

Prepare all of the shielded cables using one of the methods shown in figure 4-1. For details of the shield termination to
the connector backshell refer to figure 4-2.

1.

At the end of the shielded cable (11), strip back a 2.5" maximum length of the jacket to expose the braid.

2.

Remove the exposed braid.

3.

Carefully score the jacket 1/4" to 5/16" from the end and remove the jacket to leave the braid exposed.

4.

Connect a 20 or 22 AWG wire (13) to the exposed shield of the prepared cable assembly. Refer to figure 4-1. For
termination techniques refer to AC 43.13-1B.

5.

Slide a shield terminator (12) onto the prepared cable assembly (11).

6.

Connect the shield wire (13) to the shield using a heat gun approved for use with solder sleeves.

7.

Crimp contacts (14) onto the cable wires. Refer to section 4.1.

8.

For the remaining shielded cables, repeat steps 1 through 7 as necessary.

9.

Install a ring terminal (15) onto the cable shield termination wires (13).

10. Group wires as applicable for the connector. Refer to section 4.4.
