Amphenol Aerospace
Size 8 High Speed Quadrax and Differential Twinax
Contacts
For use in MIL-DTL-38999 Subminiature Cylindrical and
Arinc 600 Rectangular Connectors.
•
Quadrax contacts consist of an outer
contact with four strategically spaced
inner contacts forming two 100 or
150 Ohm matched impedance
differential pairs.
Differential Twinax consist of an
outer contact with two inner contacts
spaced to form one 100 or 150 Ohm
matched impedance differential pair.
