It comes as a three-piece kit — the connector body, a crimp ferrule, and a centre contact — for field termination to RG-174A, RG-188A, or RG-316 coaxial cable. The gold-plated stainless steel body resists corrosion in test-equipment and telecom environments, and the threaded coupling ensures a vibration-resistant mate. With 500 mating cycles, this plug holds up to repeated connect-disconnect in production test or field-service scenarios.
This plug accepts RG-174A, RG-188A, and RG-316 cable — the three most common small-diameter coax types for SMA applications. The PTFE dielectric in the connector matches the cable's dielectric to maintain the 50 Ohm impedance through the joint. For a field technician: the crimp tool die set must match the ferrule outer diameter for the specified cable jacket; using the wrong die can pull the shield loose under tension.
RF performance and duty
Rated to 18 GHz, this SMA plug covers the full L-, S-, C-, X-, and Ku-band spectrum used in microwave test, antenna feeds, and satellite ground equipment. The gold-over-brass centre contact and gold-plated stainless body keep insertion loss low across the band. For an RF engineer: the 18 GHz ceiling is the connector's own limit; the actual system bandwidth may be lower depending on cable loss and the mated receptacle's performance.
For a procurement buyer: the active status means you can commit the BOM line without a replacement watch, and the three-piece kit format (connector + contact + ferrule) simplifies kitting — no separate ferrule or contact line items to track.
The sibling 1-1478924-0 shares the same Greenpar SMA plug body, 50 Ohm impedance, 500 mating cycles, and RG-174/188A/316 cable group — but ships with an end cap and ferrule instead of a centre contact and ferrule. The 1-1478916-0 is the full termination kit for a male pin plug; the 1-1478924-0 is for applications where the centre contact is supplied separately or the connector is used as a dust cap.
