The PTFE dielectric and gold-plated brass centre contact maintain a consistent 50 Ohm impedance across the mated pair. ## Crimp or Solder Centre Contact — Your Choice on Termination The centre contact accepts either crimp or solder termination, giving you flexibility on the assembly line or in the field. The shield is crimped via the included ferrule over the braid.","metaTitle":"Amphenol 031-4321 BNC Plug, 50 Ohm, 4 GHz, RG-59/62/140/210","metaDescription":"Amphenol 031-4321 BNC plug, male pin, 50 Ohm, 4 GHz max, 0.2 dB insertion loss.
