Quadrax Contacts

MIL-DTL-38999, Series III, General Description

AMPHENOL QUADRAX CONTACTS

Offers 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. The Outer contact

has a rugged wall section for durability. Available in size 8 crimp termination

style. Also available in size 8 with PC tails (see pages 22-23). Requires

modiﬁcation of MIL-DTL-38999 connector to accommodate keyed contacts.

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)
