COAXIAL CONTACTS FEATURES AND BENEFITS Coax Size 12 & 16 Contact Performance: Typical VSWR: 1.5:1 maximum up to 700 MHz and 500 MHz respectively, for properly cabled size 12 and 16 coaxial contacts in the M38999 Series I, II and III Insulation Resistance: 5,000 megohms minimum @ 25° C Dielectric Withstanding Voltage: Size 12: 1,000 VAC Rms @ sea level, 250 VAC Rms @ 50,000 ft. Size 16: 800 VAC Rms @ sea level, 250 VAC Rms @ 50,000 ft. Contact Resistance: See MIL-C-39029/27, /28, /75 - 78 Coax Contacts are gold plated, crimp termination The finish of mating contacts parts (supplied with 0.000050 min.) is gold over nickel. Other finishes are available; consult Amphenol for further information. OVERVIEW Amphenol® Coaxial contacts offer several advantages for reliable interconnection and continued performance: Large crimping area assures low contact resistance and high tensile strength Back insulator positively captivates inner contact against axial loads Front insulator provides closed entry for socket inner contact Recessed inner contact is protected Outer contact has rugged wall section for durability
