The threaded coupling and crimp shield termination give a stable, repeatable RF connection for test equipment, microwave modules, and antenna feeds where the cable run is fixed after assembly. For a BOM that requires this exact SMA jack, the procurement path is the surplus and broker channel; there is no direct factory replenishment. The body is zinc with nickel finish, the centre contact is copper alloy with gold plating. The dielectric is polymethylpentene (PMP). Termination is solder for the centre contact and crimp for the shield — a standard build for semi-rigid coax where the centre conductor is soldered and the braid is crimped into the ferrule. The free-hanging, in-line mounting with threaded fastening means it mates to a bulkhead jack or panel-mount receptacle and stays put under vibration. Rated for 500 mating cycles — a solid figure for an SMA connector, indicating the gold-plated centre contact and nickel-plated body will tolerate repeated connect/disconnect in test or field-service scenarios without significant degradation.","metaTitle":"TE KOAXXA 2081205-1 SMA Jack, 50 Ohm, 18 GHz, Obsolete","metaDescription":"TE KOAXXA 2081205-1 SMA jack, 50 Ohm, 18 GHz max, for RG-402 semi-rigid coax.
