1.
Identify connector parts. (3 piece parts)
2.
Strip cable to dimensions shown. Do not nick braid or center conductor. Tin center con-
ductor if contact will be solder attached. Do not tin center conductor if contact is to be
crimp attached. When stripping LMR-100 low loss cable, remove foil back to where cable
jacket is stripped. A wire stripper of correct size is recommended for this step. Slide heat
shrink (as applicable) and crimp sleeve onto jacket of cable.
3.
Assemble contact onto cable as shown.
Solder Attachment:
Solder contact to center conductor through solder hole using .020
(0.51) diameter solder. Use a minimum amount of solder for a good joint.
Crimp Attachment:
Crimp contact to center conductor using Johnson Components
TM
Hand Tool 144-0000-910, setting #2, with positioner 141-0000-907. Crimp location should
be centered between end of contact and X-hole. Crimp attachment to solid center con-
ductor cables is not recommended.
4.
Flare braid and slide body assembly over contact and under braid. Then seat body as-
sembly firmly onto contact. The cable may have to be held in a clamping fixture. Arrange
braid uniformly around crimp stem. Slide crimp sleeve forward and crimp using recom-
mended crimp tool. Slide heat shrink forward and shrink (as applicable).
