The TE Connectivity 2-330062-1 is a Coaxicon series BNC jack — a 50 Ohm female socket connector with a bayonet lock, designed for field-termination onto RG-174 and RG-188 coaxial cable.
Rated at 50 Ohms impedance with a frequency ceiling of 2.5 GHz — this is a standard BNC, not a 75 Ohm video variant, so it matches the common 50 Ohm RF test and telecom infrastructure. The 500 V rating gives plenty of headroom for signal-level applications; the real limit in a BNC at these frequencies is the connector's VSWR, not the dielectric breakdown. The shield is crimped and the center contact pushes on — no soldering required on the signal pin, which speeds up field assembly and keeps the impedance consistent through the termination. Rated for 500 mating cycles — that's a solid count for a bayonet-lock connector, indicating it's built for frequent connect/disconnect duty like test equipment or portable gear. The silver-plated brass body provides RF shielding and a clean ground path through the shell.
