The 000-4700-51 is a 50 O BNC straight jack-jack panel mount adapter connector manufactured by Amphenol RF. It features a nickel-plated body with gold-plated contacts, designed for industrial-grade applications requiring reliable RF signal transmission. The connector operates across a frequency range of DC to 4 GHz (usable to 11 GHz) with a nominal impedance of 50 O and a maximum VSWR of 1.3 at DC–4 GHz. It employs a 2-stud bayonet lock coupling mechanism (MIL-STD-348) for quick mating and unmatting, with a coupling torque range of 0.6 to 2.5 in-lbs. This adapter is ideal for panel-mount applications in telecommunications, broadcast, instrumentation, and computer networking systems where secure, low-reflection RF connections are essential.
