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).

2B Series Connector System
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).
