Description
N Plug (Male) to SMA Jack (Female) | 4-Hole Panel Adapter | Screw-Lock | Brass Body
The ROSNOL AD-N1A25A-PF/H33-91 is designed for secure panel-mounted RF connections between N male and SMA female interfaces. It operates from DC to 11 GHz with 50 Ω impedance, VSWR ≤1.15, insertion loss ≤0.05√F (GHz) dB, insulation resistance ≥5 GΩ, working voltage 480 V rms, and power handling up to 200 W at 2 GHz. Screw-lock coupling ensures reliable engagement with axial captivation ≥28 N and ≥500 mating cycles. Hole Spacing: 18.25 mm (.719 inch). Recommended torque: 0.7–1.1 Nm.Contacts are beryllium copper with gold plating over nickel-phosphorus underplating; bodies brass with nickel plating; insulators PTFE; gasket silicone rubber; coupling nut nickel-plated brass. The adapter withstands −65°C to +165°C and complies with RoHS.
ROSNOL’s precision-engineered RF components offer high quality and consistent performance at competitive pricing, making them a strong alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001–certified facilities and are fully compliant with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
