Quadrax Contacts, MIL-DTL-38999, Series III
General Description
TYPICAL QUADRAX
SOCKET CONTACT
has socket outer contact
with a socket inner contact
TYPICAL QUADRAX PIN CONTACT
has pin outer con tact with a pin
inner contact
Quadrax Pin Size 8 and MIL-DTL-38999
Series III Connector
Also see Quadrax contacts for ARINC 600 and R27
Rack and Panel Connectors on pages 265 and 266.
Suggested Strain Relief - Insert Arrangements
9-5 or 19-18 with Quadrax Contacts
Due to the piggyback grommet interference with normal strain reliefs
on the shell size 9 only, the recommended strain relief for the
connector is: Amphenol part number TGW-R-5309-10 (OD Cad) or
TGF-R-5309-10 (Electroless nickel) - shell size 9 only. For 19-18 insert
pattern, recommended backshell: Glenair 367-221-NF. This is
recommended due to the proximity of the size 8 contacts in relation
to the shell.

Suggested Numbering for Quadrax
Contacts
Differential Pairs, contacts 1-3, 2-4.
See page 243 for part number ordering of
popularly used 38999 Series III connectors with
100 ohm quadrax contacts.
Quadrax differential pairs are 1 and 3, 2 and 4.
Quadrax Contacts are gold plated,
crimp termination
Finish of mating contact parts: supplied with
0.000050 min. gold over nickel on mating
parts. Consult Amphenol for availability of
other nishes.
Quadrax Size 8 Contact Performance:
• Bandwidth: Up to 1.25 GHz
• Data Rate: Exceeding 2.5 Gbps.
• Voltage Rating: 500 Vrms max. @
sea level
• Dielectric Withstanding Voltage:
1000 VAC rms between all inner contacts
@ sea level, 500 VAC rms between inner
and outer contacts @ sea level
Amphenol® Quadrax Contacts -Offer several
advantages for high data transfer rates, low power consumption and
excellent
EMI compatibility:
• Four strategically spaced inner contacts form two 100 or 150
Ohm matched impedance differential pairs
• Outer contact has rugged wall section for durability
• Available in size 8 crimp termination style
• Also available in size 8 with PC tails (see page 233)
• Requires modication of MIL-DTL-38999 connector to
accommodate keyed contacts
Guide for selecting a Backshell:
When ordering backshells, to avoid interference between the piggyback
grommets which are used on all size 8 cavities and the backshell the below
keepout dimensions must be adhered to. (based on existing arrangements)
