Cable preparation
First place the strain relief (if to be used) on the cable.
Strip the cable according to dimensions below.

Cable termination
2.1 Place crimp ferrule
on the cable. Widen the shield braid. Slide the
subassembly
into the cable until the insulator rests against the
dielectric and the cable conductor is visible through the contact ins-
pection hole.
2.2 Crimp the contact with the LEMO crimping tool using the square
hole (see “Tooling” on page 32).
Gently pull the cable in order to check the crimping.
2.3 Slide the crimp ferrule
onto the braiding until it rests against the
crimp backnut of the subassembly
. Crimp with the same LEMO
crimping tool using the hexagonal opening.
Slide the insulator
onto the subassembly
.
2.4 Slide the assembly into the connector shell
and screw it onto the
subassembly
. Tighten using the appropriate tool to a torque of
0.25 Nm (see “Tooling” on page 31 and 32). Push the strain relief (if
used) onto the crimp ferrule
.
