It is the single-port, right-angle, through-hole panel-mount member of the 5227161 base series, with a bayonet lock coupling that gives a quick, tool-less mate and positive retention under vibration.
The 4 GHz maximum frequency covers common wireless, test equipment, and instrumentation bands up to the lower microwave range; above that, the BNC interface geometry introduces mode conversion and the VSWR rises. The 500 V rating gives headroom for RF applications where the signal rides on a DC bias, but the practical limit in a 50 Ohm system is set by the power handling of the centre contact and dielectric — the PMP insulator handles the voltage, not the current. The right-angle, through-hole termination with solder shield termination means the centre pin and the outer braid both solder to the PCB — no crimp barrel, no separate ground lug. The nickel body finish on the zinc shell provides the primary corrosion barrier for the RF shield path.
This BNC jack is used as a board-edge RF interconnect in test equipment, instrumentation, telecom base stations, and industrial RF systems where a 50 Ohm controlled-impedance path is required. The panel mount with bulkhead nut suits enclosures where the connector must be mechanically fixed to the chassis before the PCB is assembled — common in benchtop instruments, RF amplifiers, and signal generators.
