It is a free-hanging, cap-style plug — terminated to the cable end, not to a panel or PCB. The body is machined brass with a nickel finish, and the centre pin is gold-plated brass for reliable signal transfer and corrosion resistance. A built-in lanyard provides a pull-tab for quick disconnect in field-service or test-equipment applications. The connector uses a brass body and centre contact, with a nickel body finish and gold contact finish. The dielectric material is polyethylene (PE). These materials are standard for general-purpose BNC interconnects in indoor, dry environments. The gold-plated centre pin supports repeated mating cycles without signal degradation. The free-hanging cap mount design means it terminates to the cable end — typically via crimp or clamp attachment to the coaxial cable's centre conductor and braid. The lanyard feature aids manual unmating in tight spaces or where frequent reconnection is needed.","metaTitle":"TE Connectivity 221629-1 BNC Plug, 50 Ohm, Lanyard, Obsolete","metaDescription":"TE Connectivity 221629-1 BNC plug, male pin, 50 Ohm impedance.
