DESCRIPTION

031-239 is a front mount bulkhead panel jack BNC connector designed for pressurized RF applications. It features a nickel-plated brass body with silver-plated beryllium copper or phosphor bronze female contact, and utilizes a solder cup terminal type for reliable circuit board integration. The connector operates across a temperature range of -65°C to +165°C and supports RF performance up to 11 GHz with low reflection through 4 GHz, making it suitable for miniature to subminiature coaxial cable termination (RG-58, RG-59, RG-179, RG-316, etc.). The 2-stud bayonet lock coupling enables quick connect/disconnect with a quarter-turn mating cycle, while the pressurized design ensures enhanced sealing for demanding environments. This industrial-grade connector is ideal for cable termination in RF systems requiring robust, hermetically sealed connections.
