Overview |
|
|
|
We developed the MIL-C-26482 Series II type connectors
with our accumulated technology.
These small sized
connectors are available for many applications, from
the leading edge communication systems to the most stringent
high reliability aerospace and missile requirements.
These
connectors shield EMI completely, thus they provide
a very stable signal lines without any interference.
Since
the connector to cable is made by using simple crimping
tool, the errors due to soldering can be avoided and
the manufacturing efficiency is increased.
|
|
Application |
|
|
|
Airplane, tank, missile, ship communication system,
medical instrument, robot and high tech industry equipment.
