Description
SMA Plug (Male) to Precision N Jack (Female) RF Adapter | Screw-lock | Brass Body
The ROSNOL ASL-A1PCN25A/111-H3 is a high-performance L-type RF adapter featuring SMA plug to precision N jack configuration, designed for signal transmission up to 18 GHz. With a 50Ω impedance and VSWR ≤ 1.20 (≥ 20.8 dB), it ensures stable signal integrity and low reflection. The adapter supports RF leakage suppression ≥ 90 dB up to 1 GHz and withstands test voltages up to 1000 V rms. Mechanical reliability includes ≥ 500 mating cycles per side, axial contact captivation ≥ 28 N, and torque ratings of 0.80–1.10 Nm (SMA) and 0.70–1.10 Nm (N). Operating temperature ranges from −65°C to +165°C, compliant with IEC 61169-1 standards for thermal shock, vibration, corrosion, and moisture resistance.The SMA side features a brass body and coupling nut with 3 μinch gold plating over 80 μinch non-magnetic nickel-phosphorus underplating. The precision N side includes a phosphor bronze center contact with identical plating, a brass body with nickel finish, and PTFE insulators on both ends. Silicone rubber gaskets are used for environmental sealing on the SMA side.
ROSNOL’s precision-engineered solutions offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment. Customization services for materials, plating, and mechanical design are available to support specialized requirements across a wide range of RF and microwave applications.
