The threaded coupling nut provides a secure, vibration-resistant mate to any standard SMA jack. ## Cable prep and termination checklist This connector accepts RG-174, RG-179, RG-187, RG-188, and RG-316 cable. The stainless steel body resists corrosion in field-service environments. With 500 mating cycles on the spec, it handles repeated connect-disconnect in test or portable equipment without degrading the RF interface. ## Sourcing an obsolete SMA plug For a new design, a parametric search on SMA plugs with the same cable group, 50 Ohm impedance, and 12.4 GHz ceiling will surface current-production alternatives; verify the interface dimensions and cable-prep method before substituting.","metaTitle":"TE Connectivity 1056443-1 SMA Plug, 50 Ohm, 12.4 GHz","metaDescription":"TE 1056443-1 SMA plug, male pin, 50 Ohm, 12.4 GHz max.
