Triax Contacts
General Description, Contact Part Number Guide by Cable
AMPHENOL TRIAX CONTACTS
Provide additional shielding 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:
Triax Size 8 Pin Contact
• 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
