Amphenol
The popular Amphenol® MIL-C-38999
Series I and II (LJT and JT respec-
tively) are also available in solder ver-
sions as both commercial parts and
military qualified to MIL-C-27599.
Amphenol JT/LJT MIL-C-27599 solder
contact connectors offer the following
benefits:
• Lightweight, space saving design
• Contact protection - 100%
scoop-proof LJT design prevents
bent pins and short circuits during
mating
• Quick positive coupling - 3 point
bayonet lock system
• Mismating eliminated - with 5
key/keyway design
• Error proof alternate positioning -
insured by different key/keyway locations
• EMI shielding - grounding figures
standard in LJT Series; optional in JT Series
• Nine Shell sizes and a variety of shell styles
• Fully intermateable and intermountable with
MIL-C-38999 Series I and II, as applicable, crimp type
connectors
The JT/JLT solder type connectors use a rigid, hard
dielectric insert which is molded around the pin and
socket contacts. This permits pressurization of 1 atmo-
sphere across an interface with a leak rate up to 1 X 10-3
cc/sec. See page 7 for classes. Contact positional toler-
ances are also considerably reduced with less chance of
pin bending. Standard solder tools are all that is required
to terminate these connectors. Continuous operating
temperature is rated at 175°C (302°F).
This publication provides dimensional data and how to
order information on the shell styles available in solder
type JT/LJT connectors. For insert availability of these
solder contact connectors refer to Amphenol catalog
12-090, JT/LJT Subminiature Cylindrical Connectors. A
complete line of accessories is also available.

tors or for any special application needs, contact your
