The 000-79100 is a hermetic TNC jack-to-jack bulkhead adapter used for creating a sealed, panel-mounted RF passthrough. It is characterized by a nominal impedance of 50 Ohms and is built for high durability, rated for a minimum of 500 mating cycles. Constructed with a nickel-plated brass body, silver-plated Beryllium Copper contacts, and PTFE insulators, the adapter operates reliably across a wide temperature range from -65°C to +165°C. This robust construction makes it ideal for use in harsh environments requiring a secure and sealed coaxial connection, such as in telecommunications, aerospace, or industrial equipment.
