031-206 is a BNC straight bulkhead clamp jack connector designed for 50O RF applications. It features a nickel-plated brass body with silver-plated beryllium copper or phosphor bronze female contact, utilizing a clamp attachment method for the outer conductor and solder termination for the center conductor. The connector supports frequencies from DC to 4 GHz with a maximum VSWR of 1.5 + 0.1f (GHz) and provides excellent shielding effectiveness of 55 dB minimum at 3 GHz. With a temperature operating range of -65°C to +165°C, coupling torque of 0.6 to 2.5 in-lbs, and a minimum durability rating of 500 mating cycles, this industrial-grade connector is ideal for panel-mount applications in test equipment, communications systems, and RF instrumentation where reliable, low-loss signal transmission is required.
