N Plug (Male) to TNC Jack (Female) | Straight Adapter with Venting Hole | Screw-Lock | Brass Body

The ROSNOL TVAC-AD-N1T25A/H44-H4 is a specialized RF adapter designed for thermal vacuum (TVAC) applications, ensuring reliable connectivity between N plug male and TNC jack female interfaces. It operates from DC to 10 GHz with 50-ohm impedance, VSWR ≤ 1.20, and insertion loss ≤ 0.05√F (GHz) dB. Electrical performance includes insulation resistance ≥ 5 GΩ, power handling ≥ 600 W at 235–275 MHz, and peak power handling ≥ 2400 W at 25% duty cycle. The adapter features screw-lock coupling on both sides, axial captivation ≥ 28 N, and supports at least 500 mating cycles. Recommended torque is 0.7–1.1 Nm for the N side and 0.46–0.69 Nm for the TNC side.

Material construction ensures superior performance under vacuum conditions. Both center contacts are phosphor bronze with gold plating over nickel-phosphorus underlayer; bodies are brass with copper-tin-zinc alloy finish, and insulators are PTFE. Silicone rubber gaskets and brass coupling nuts provide environmental sealing. The adapter is qualified for vacuum levels better than 10⁻⁵ torr and operates in temperatures from -40°C to +65°C.

ROSNOL’s precision-engineered RF adapters deliver high quality and dependable performance at competitive pricing, making them an ideal alternative to leading European and American brands. All ROSNOL components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to meet specialized interconnect requirements.
