50-Ohm SMA Plug for RG-405 Semi-Rigid Cable
The Amphenol RF 901-9201-2ASF-T is a 50-Ohm SMA plug, male pin, designed for RG-405 (.085".086" semi-rigid) cable. It is a threaded, weatherproof connector rated to 18 GHz with a stainless steel body, gold and passivated finish, and a gold-plated beryllium copper center contact. Typical use is in RF/microwave interconnects for test equipment, antenna feeds, and outdoor enclosures where a stable 50-Ohm impedance and weather resistance are required.
18 GHz Bandwidth with Weatherproof Construction
The 50-Ohm impedance and 18 GHz max frequency make this plug suitable for high-frequency signal paths up to Ku-band. The weatherproof rating means the mated pair resists moisture and dust ingress, useful for outdoor antenna or remote radio head connections. The stainless steel body and gold/passivated finish provide corrosion resistance for field-deployed or marine environments.
Build-to-Print Kit: Connector, Contact, Insulator
The contact and insulator are pre-assembled into the body during cable termination. For a complete build-to-print BOM, you also need the mating SMA jack (e.g., 901-144 receptacle) and the RG-405 cable.
500 Mating Cycles and Threaded Fastening
The threaded fastening (6 mm hex nut) ensures vibration-resistant engagement — no snap-on or bayonet that could loosen under shock. This makes the plug a good fit for test cables, portable equipment, or any application where the connector is reconnected regularly.
