Description
3.5mm Plug (Male) to 3.5mm Jack (Female) Adapter | Straight Design | Screw-Lock | Stainless Steel Body
The ROSNOL AD‑PC1PC25A/9XX‑9X is a high‑precision 3.5mm Plug (Male) to 3.5mm Jack (Female) adapter engineered for stable RF performance from DC to 34.5 GHz. Designed with a 50‑ohm impedance, a low VSWR of 1.15, high insulation resistance of at least 5 GΩ, and a test voltage rating of 1000 V rms, this adapter ensures reliable low‑loss signal transmission for demanding high‑frequency systems. Additional electrical stability is supported by a return loss of 23.13 dB or higher and minimized insertion loss, making it suitable for microwave‑band interconnects in advanced measurement and communication environments. The mechanical structure incorporates a screw‑lock coupling mechanism, a durability rating of at least 500 mating cycles, a center‑contact captivation force of 27 N or greater, and a recommended torque range of 0.80 to 1.10 Nm.The adapter is constructed with a beryllium copper center contact plated with gold over a non‑magnetic nickel‑phosphorus underplating to ensure excellent conductivity and long‑term corrosion resistance. Its stainless‑steel body and coupling nut feature passivated finishing for enhanced mechanical strength, while the PEI insulator and silicone rubber gasket provide stable dielectric performance and environmental sealing. These materials make the AD‑PC1PC25A/9XX‑9X suitable for high‑frequency laboratory instrumentation, precision RF test platforms, microwave communication systems, and applications requiring mechanical compatibility with 2.92mm and SMA connectors.
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.
