4.3 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. Refer to figure 4-2 for
details of the shield termination to the connector backshell.
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. AC 43.13 maybe a helpful reference for termination techniques.
5. Slide a shield terminator (12) onto the prepared cable assembly (11) and connect the shield wire
(13) to the shield using a heat gun approved for use with solder sleeves.
6. Crimp contacts (14) onto the cable wires. Refer to section 4.1.
7. Repeat steps 1 through 6 as necessary for the remaining shielded cables.
8. Install a ring terminal (15) onto the cable shield termination wires (13).
9. Group wires as applicable for the connector. Refer to section 4.4.
