Coaxial Contacts for MIL-DTL-38999
General Description
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
