Amphenol
provide high speed transmission and
operate in high frequency conditions
When you need superior electrical performance plus shielding to eliminate
interference from outside electrical sources in a connector, Amphenol has the
most reliable contact solutions.
Amphenol offers a very wide range of contacts that provide high speed transmis-
sion and operate in high frequency conditions. You can be assured of interconnec-
tion compatibility when you come to Amphenol for your contact needs as well as
your connector needs. Amphenol’s expertise in interconnection solutions assures
that your contacts will mate properly and will perform to the application specifica-
tions of your particular requirements.
MIL-DTL-38999 CONNECTORS - The high performance series most ideal for
integrating high speed and high frequency contacts. MIL-DTL-38999, Series I, II
and III are by far the choice of connector for today’s avionics needs - these
subminiature family connectors are ideally suited for the incorporation of
shielded contacts.
This catalog is primarily devoted to the high speed and high frequency contact
options for use in MIL-DTL-38999 Connectors, which include:
Other series of connectors from Amphenol Aerospace, in addition to 38999 connectors, can
incorporate shielded contacts. These include the following (and are also covered in this
catalog):
• Amphenol
• Amphenol
• LRM Interconnects - Rectangular module and backplane connectors with standard low
• Amphenol
The Cable Usage Guide is a key reference to help guide you in selecting the contacts best
suited to your needs. Since most shielded wire applications start with a fixed requirement for
cable types, the guide refers you to the Amphenol connector family utilizing contacts which
are compatible with the cable characteristics.
