The 031-9-75RFX is a 75 O BNC angle jack-plug adapter designed for commercial-grade RF connectivity applications. This connector features a nickel-plated brass body with gold-plated beryllium copper or phosphor bronze contacts, providing excellent corrosion resistance and reliable signal transmission. The adapter operates across a frequency range of DC to 1 GHz with a nominal impedance of 75 O, delivering a VSWR of 1.0 + 0.25f (GHz) and insertion loss of 0.2 dB maximum at 3 GHz. It employs a 2-stud bayonet lock coupling mechanism (MIL-STD-348) with a coupling torque range of 0.6 to 2.5 in-lbs, ensuring secure mating with quarter-turn engagement. The connector is rated for operation from -65°C to +165°C and supports 500 mating cycles minimum, making it suitable for test equipment, instrumentation, and video/RF signal distribution systems requiring 75 O impedance matching.
