Amphenol's 031-6-RFX BNC connector is a miniature, lightweight RF connector developed in the late 1940s. It utilizes a bayonet coupling mechanism for quick and reliable connections, making it ideal for applications requiring frequent connection and disconnection. Commonly used with RG-58, 59, RG-179, and RG-316 coaxial cables, this connector finds applications in test instrumentation, medical equipment, and various communication systems. Amphenol offers both 50Ω and 75Ω BNC connectors to meet diverse impedance matching needs, with options for military-grade (MIL-C-39012) and commercial applications.
