The BIRNS Millennium 3P is a very popular larger-midsize connector, available with 13 to 83 contacts. The 3P is available in alternate materials Ni-Cu (K-Monel, class A) and Ti.
The 3P is available in coaxial formats (50Ω and 75Ω), with top quality polyethylene dielectrics and gold-plated Be-Cu sockets. BIRNS’ new coax contacts have a maximum insertion loss of 0.7 dB at signal frequencies to 3GHz, with an associated maximum SWR of 1.7:1 and withstand open face hydrostatic pressure to depths of 1433m so far in initial testing protocols, with more testing currently under way. This new design provides incredible ease of assembly and connects directly to a standard MIL-STD-348 SMA connector. We are converting our lines of coax connectors to include these revolutionary new contacts, and currently offer them in the 3P-1C and 3P-2C6 configurations.
