1. Identify connector parts. (3 piece parts)
2. Strip cable to dimensions shown. Do not nick braid or cen-
ter conductor. Tin center conductor if contact will be solder
attached. Do not tin center conductor if contact is to be
crimp attached. A wire stripper of correct size is recom-
mended 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 hole using a minimum amount of solder for a good
joint.
Crimp Attachment (where applicable):
Crimp contact to
center conductor using recommended crimp hex.
4. Flare braid and slide body assembly over contact and un-
der braid. Then seat body assembly firmly onto contact.
