  • Small size for high density packaging
  • Ideal for RF and microwave applications for instruments, radar, communications, and RF shielding
  • Interface Dimensions for MIL-DTL-38999, ARINC 404 and ARINC 600 Per SAE-AS39029

Coaxial contacts provide flexibility in the design of high frequency RF and micro-wave applications. The contacts, including sizes 5, 8, 9, 12 and 16 and have the same outline dimensions as traditional power contacts that fit  various insert arrangements for d-sub, circular, and rack and panel connectors. The coaxial cable type contacts are designed for low-loss concentric 50 and 75 Ohm cable types.

An innovative design of coax contacts opens a whole new world of design options. These small, rugged contacts have a VSWR rating of 1.3:1 max with a frequency range from DC to 5 GHz.
