The 031-6575: It is a bulkhead-mount part with right-angle through-hole PCB tails, so it secures to a panel cutout via the front-side nut and then solders into the board in one pass. The dual-port configuration means this single order code covers two BNC positions on one body, saving placement time on multi-channel RF boards.
Mounting and Termination — Panel and PCB in One Assembly
The right-angle PCB tails then solder into the board, so the connector serves as both the panel seal and the board interconnect. The shield termination is solder as well — no separate ground tab or crimp ferrule.
RF Performance and Contact Duty
Rated to 1 GHz with 0.2 dB insertion loss, this jack suits baseband, video, and lower-frequency RF signal paths — not high-bandwidth data links above 1 GHz. The 50 Ohm impedance is standard for test equipment, telecom, and broadcast.
Board Lock and Isolation Features
The polypropylene insulator isolates the two centre contacts from each other and from the shell, maintaining the 500 V rating between ports.
