Description
SMB Plug (Male) to TNC Jack (Female) | Straight Adapter | Snap-On & Screw-Lock | Brass Body
The ROSNOL AD-S1T25A/911-94 is a precision RF adapter designed for DC to 4 GHz operation with 50 Ω impedance. It achieves VSWR ≤ 1.35 and insertion loss ≤ 0.05√F (GHz) dB, ensuring stable signal transmission and minimal loss. Insulation resistance is ≥1 GΩ, and the adapter supports ≥500 mating cycles on both sides. Coupling mechanisms include snap-on for SMB and screw-lock for TNC, with center contact captivation ≥10 N for SMB and ≥15 N for TNC.Center contacts are beryllium copper with 3 microinch gold plating over an 80 microinch nickel-phosphorus underplating. Bodies and coupling nuts are brass with corrosion-resistant finish, and insulators are PTFE. Recommended torque for the TNC side is 0.46–0.69 Nm. The operating temperature range spans −65°C to +165°C, ensuring durability under harsh conditions.
ROSNOL’s precision-engineered RF adapters deliver exceptional electrical performance, mechanical reliability, and cost efficiency. Designed to meet stringent RF industry standards, they provide superior durability and consistent signal integrity even in demanding environments. All components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards. ROSNOL offers customization for materials, plating, and mechanical design, ensuring tailored solutions for specialized applications and competitive alternatives to leading global brands.
