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 and crimp

SE 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

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

terminated to other than 50 ohm cables are therefore not matched.

PT-SE Type III is 50 ohm contact, non-serviceable after assembly.

Solders are non-impedance matched contacts.
