Cable termination

2.1 Place the collet nut 

➀ 

and the collet 

on the cable. Fold back the

shield braid onto the conical part of the collet, and trim to the outer
edge of the collet

2.2 Slide the subassembly

2.4 Slide the assembly into the connector outer shell 

. Screw the

collet nut 

into the connector outer shell 

using the appropriate

tool and tighten to a torque of 0.25 Nm (see “Tooling” on page 35,
36 and 37). Push the bend relief (if used) onto the collet nut.

2.2 Crimp the contact with the LEMO crimping tool using 

the square hole (see “Tooling” on page 37).
Gently pull the cable in order to check the crimping. 

2.3 Slide the crimp ferrule 

➀ 

onto the shield until it rests against 

the crimp backnut of the subassembly 

. Crimp with the same

LEMO crimping tool using the hexagonal opening.
Slide the insulator

2.4 Slide the assembly into the connector shell 

and screw it 

onto the subassembly
