Triax Contacts for MIL-DTL-38999
General Description, Application Data
Amphenol^® Triax Contacts -Provide additional shielding
when terminated to triax cable having solid or stranded center con­
ductors. 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
