1.85 mm Jack (Female) to 1.85 mm Jack (Female) | Bulkhead Adapter | Screw-Lock | Stainless Steel Body

The ROSNOL AD-V2V25A-BH/9X-9X is a high‑frequency bulkhead adapter specified at 50 Ω for DC to 65 GHz operation. It delivers VSWR ≤ 1.25, insertion loss ≤ 0.4 dB, insulation resistance ≥ 5 GΩ, center contact resistance ≤ 4.0 mΩ, and outer contact resistance ≤ 2.5 mΩ. Electrical ratings include test voltage 500 V rms, working voltage 150 V rms, and RF leakage ≥ 100 dB up to 1 GHz. The screw‑lock mechanism provides secure coupling with center‑contact captivation ≥ 20 N, a coupling test torque of 1.65 Nm, recommended torque 0.80–1.10 Nm, and 2.5 Nm for the hexagon nut, supporting consistent performance in ultra‑wideband applications.

Materials and plating: center contacts are beryllium copper with gold plating; the body is stainless steel with passivation for corrosion resistance; the insulator is PEI for excellent dielectric stability. A silicone rubber gasket enhances sealing, and the fastening nut and washer are stainless steel with passivation for mechanical robustness. The operating temperature range is −55°C to +165°C.

ROSNOL’s precision-engineered RF adapters deliver reliable performance across RF and microwave systems. Designed to meet the stringent demands of high‑frequency signal transmission, ROSNOL adapters offer a cost‑effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001‑certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
