Coaxial Contacts
for miniature cylindrical connectors, cont.
Amphenol ? Coaxial Contacts designed for use in Miniature Cylindrical Connectors
offer the same durability advantages and design benefits for reliable interconnection as the
Amphenol coax contacts used in high performance D38999 connectors. A variety of military
and commercial shielded cables are accommodated within the miniature cylindrical series.
Amphenol supplies coax contacts for solder, crimp SE and crimp CE connector styles.
Other features of the coax for miniature cylindricals include:
? Miniature coax design has an outside nut within the
assembly for fast, reliable assembly of contact to cable.
? All types feature solder style inner contacts and crimp
style outer contacts for reliable cable termination
? Miniature coax crimp type contacts are designed for use
in Miniature crimp series connectors
? Miniature coax solder type contacts are designed for
use in Miniature solder series connectors. These
come pre-installed into the solder connector.
TYPICAL ELECTRICAL PERFORMANCE
Size 8 and 12 Coax Contacts
Contact Resistance:
Center @ 1 Amp, 170 millivolts max. voltage drop @ 25°C
Outer @ 12 Amps, 150 millivolts max. voltage drop @ 25°C
TYPICAL MINIATURE CRIMP COAX
SOCKET CONTACT has crimp socket outer
contact with a solder pin inner contact
TYPICAL MINIATURE CRIMP COAX PIN
CONTACT has crimp pin outer contact
with a solder socket inner contact
Dielectric Withstanding Voltage:
Size 8: 1,300 VAC Rms @ sea level
Size 12: 1,000 VAC Rms @ sea level
Size 8 & 12: 250 VAC Rms @ 50,000 ft.
Insulation Resistance
5,000 megohms minimum @ 25°C
Typical VSWR for size 8 & 12 PT-SE Types II & III only:
1.2 + .12F (GHz) up to 10 GHz
EXPLANATION OF TYPE CLASSIFICATIONS:
PT-SE Type I is moisture seal design with internal O-ring.
PT-SE Type II is 50 ohm impedance matched version. Contacts ter-
minated to other than 50 ohm cables are therefore not matched.
PT-SE Type III is 50 ohm contact, non-serviceable after assembly
Solder and CE Types are non-impedance matched contacts.
