50 Ohm BNC Plug — Male Pin, Free-Hanging Cap Termination
The 221629-4: Gold contact finish on a brass body with nickel plating; the dielectric is polyethylene. This is a free-hanging, cap-style plug — no panel mount, no PCB tails, just a cable-end termination that twists and locks.
The free-hanging cap design means it terminates the cable end; no board footprint or panel cutout to match.
