SMA Plug (Male) Straight Cable Connector for RG58, RG303, RG141, LMR195, RNL195, DC-5GHz VSWR 1.20

SMA Plug (Male) | Crimped Cable Entry | Screw-lock | Brass Body

The ROSNOL SMA1C50-G058A/144 is a precision-engineered SMA plug (male) straight cable connector designed for reliable RF signal transmission in 50 Ω systems. This connector operates over a frequency range from DC to 5 GHz and features a screw-lock coupling mechanism to ensure secure mating and stable electrical performance. The connector supports a crimped cable entry and a center contact that can be either soldered or crimped, providing flexibility during cable assembly. With a VSWR of ≤ 1.20 and low insertion loss characteristics, this SMA connector is suitable for applications requiring consistent impedance control and signal integrity. Mechanical performance includes a recommended coupling torque of 0.57 Nm, a maximum coupling torque of 1.7 Nm, and a minimum of 500 mating cycles, ensuring durability in repeated connection environments.

The connector body is manufactured from brass with a copper–tin–zinc alloy composition to provide mechanical strength and corrosion resistance. The center contact is made of brass with gold plating over a non-magnetic nickel-phosphorus underplating to enhance conductivity and long-term stability. The insulator is PTFE for excellent dielectric performance, while the gasket is constructed from silicone rubber to support environmental sealing. The coupling nut and crimp ferrule are also produced from brass copper–tin–zinc alloy. The SMA1C50-G058A/144 is compatible with RG58, RG303, RG141, Times Microwave LMR 195, and ROSNOL RNL 195 cables, making it suitable for a wide range of RF cable assemblies.

ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment.
