Highest Reliability Electronic Connectors For Advanced Applications
About The Series
The T9 Series is our most technologically advanced series of cylindrical connectors available. T9 connectors can accommodate the highest density of contacts in one connector and feature the most comprehensive selection of contacts available, including fiber optic, twinax, coax, quadrax, and PC tail contacts. Coupling is achieved with one 360° turn of the self-locking coupling ring, which is designed with triple-start, impact-resistant stub threads. Standard RFI grounding fingers provide superior shell-to-shell conductivity for shielded applications, while available stainless steel shells protect connectors during rough handling or extreme temperatures. For applications that demand the absolute best, T9 connectors are the only choice.
The T9 Series also offers hermetic receptacles for vacuum chambers or other pressurized applications and connectors manufactured from space-grade aluminum components and thermoplastic composite that meet NASA specifications.
For additional help in specifying your connector solution, please contact a Milnec sales professional, or your authorized distributor for technical and sales support.
