QUADRAX CONTACTS FOR
ARINC CONNECTORS
Amphenol ARINC 600 Rack and Panel
connectors can incorporate high speed
quadrax contacts as well as coax, twinax
and differential twinax contacts. R27 Rack
and Panel connectors use the same
contacts as ARINC 600 connectors. See
Cable Usage Guide and see pages 47
and 48 for more information on these rack
and panel connectors.
BOARD LEVEL CONNECTORS
WITH COMPLIANT QUADRAX
CONTACTS
Amphenol also provides compliant
quadrax socket contacts and Quadrax pin
contacts with PC tails for attaching to
printed circuit boards. See page 17 for
more information.
FEED-THROUGH CONNECTOR
WITH QUADRAX CONTACTS
Amphenol’s feed-through connector is
double-ended for through bulkhead
applications. Consult Amphenol for more
infomation.
Quadrax Terminators
Amphenol offers a termina-
tor assembly which is a low
reactance, resistive
impedance match to the
characteristic impedance of
a transmission line. It is
used to terminate the far ends of a transmission
line or an open tap so that the energy from signals
traveling down the transmission line is absorbed
within the resistor and not reflected back down the
transmission line causing signal interference
(noise). Consult Amphenol for more information.
Transition Adapters
In conjunction with its Differential Twinax and Quadrax contacts,
Amphenol has developed a full line of Transition Adapters in order
to facilitate launching of controlled impedance signals to printed
circuit boards. These use differential twinax or quadrax 90° or
straight receptacles and they can be either threaded or cable to
board direct. The threaded transition adapters provide an ideal
method of disconnecting the differential twinax or quadrax
connector from the board. See pages 18-20 for further
description, performance data and ordering of transition
adapters.
