10602 (Twinax)
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
