The following procedures are based on Gore’s best practices for
terminating GORE
®
Aerospace Ethernet Cables with the LEMO
®
2B Series Connector System for both plug (pin) and socket
versions. Following these procedures will enable you to maximize
the performance of your assembly; however, results may vary
depending on the specific application.
Preparing the Cable and Parts
1. Gather the tools and materials required for assembly and
termination (Figures 1 – 6).
2. Be sure to evaluate the tools and procedures in these termination
instructions for potential hazards; collect the proper personal
protective equipment you will need.
3. Verify that you have the correct parts for your assembly by
checking the part numbers for the connectors and the GORE
®
Aerospace Ethernet Cables listed on drawing DDA0238.
4. Cut a piece of cable to the desired assembly length minus 3.6 cm
for the length of the connectors you are terminating:
• 2.0 cm for the plug connector
• 1.6 cm for the socket connector
5. Print any labels required by the end-user, and slide the center
label onto the cable.
6. To identify the end of the plug connector, place a piece of tape
on the end in which the pairs rotate clockwise in order of
green
brown blue orange (Figure 7).

Preparing the Plug Connector
1. With the small end nearest the cable, slide the connector cap
onto the cable (Figure 8).

2. With the smallest end near the cable, slide the collet nut over
the cable; then slide the collet over the cable with the teeth
facing the collet nut (Figure 9).
3. Measure and mark the cable 0.5 inch from its end (Figure 10).
4. Using a scalpel or scissors, slit the cable’s jacket from its edge
to the mark (Figure 11).
5. Using needle-nose pliers, gently pull the outer jacket down the
cable until you have exposed approximately 1.5 inches of braid
(Figure 12).
6. With your fingers, push the braid back over the cable to expose
approximately 1.5 inches of the foil (Figure 13).
