Amphenol® Triax Contacts-Provideadditionalshielding

when terminated to triax cable having solid or stranded center

conductors Amphenol supplies triax contacts in sizes 8, 10 and 12

and they are ideally suited for use in D38999 Series I, II and III

circular connectors

Features and benefits of Amphenol triax contacts include:

• Incorporates three conductors, designed for use with triax cable

• Each of the three conductors are separated by dielectric

insulation to isolate ground planes

• Shielding effectiveness is improved with two isolated shields

• May be specified for direct connection to printed circuit boards

• May be mixed with coax, twinax and power contacts in a

single connector
