It uses a bayonet lock for quick, positive mating — the standard BNC coupling that gives a half-turn engagement and disengagement without tools. This is a single-port, 50 Ohm nominal impedance connector rated to 4 GHz, which puts it in the general-purpose RF interconnect class: suitable for test equipment, instrumentation, telecom infrastructure, and video distribution where the signal path stays below the 4 GHz ceiling. The 500 V rating is notably higher than many BNCs, so it can handle RF power or high-voltage test signals without derating concerns at the interface.
The 4 GHz max frequency covers the common bands for cellular (up to 2.7 GHz), Wi-Fi (2.4 GHz), GPS (1.575 GHz), and broadcast video — but it stops short of 5G mmWave or 6 GHz Wi-Fi 6E bands, so check the signal edge rates. The through-hole mount gives a stronger mechanical anchor than SMT for a coaxial connector that sees cable strain, and the zinc body with tin finish provides the RF shield path through the solder termination to the ground plane.
