1. Identify connector parts. (2 piece parts - except bulkhead)
2. Strip cable to dimensions shown. Do not nick braid or
center conductor. A wire stripper of correct size is rec-
ommended for this step. Twist stranded center conduc-
tor into tight bundle and tin. Slide crimp sleeve onto cable
as shown.
3. Flare braid and slide cable into body making certain that
the cable insulation bottoms in center contact.
Solder Attachment:
Solder center conductor to contact
through the side access ports and hole in center contact.
Use a minimum amount of solder for a full fillet joint.
.020
(0.51) diameter solder is recommended.
Crimp 50 Ohm connector contacts with 141-0000-911
dieset in 144-900 tool frame. Crimp 75 Ohm connector
contacts with 141-0000-924 dieset in 144-0000-900 tool
frame.
