Description
1.85mm Plug (Male) | Field Replaceable | Screw-lock | Stainless Steel Body
The ROSNOL V1BT50-0009B/9XX connector is a high-frequency field-replaceable solution engineered for demanding RF and microwave applications. Featuring a screw-lock coupling mechanism, it supports 50 Ω impedance and operates from DC to 67 GHz with VSWR ≤ 1.25 (≥19.08 dB return loss). Electrical performance includes insertion loss ≤ 0.05 × √F(GHz) dB, insulation resistance ≥ 5 GΩ, and test voltage up to 500 V rms. The connector is rated for 150 V rms working voltage and ensures RF leakage ≥100 dB up to 1 GHz.Constructed for durability, the center contact is made of beryllium copper with gold plating over non-magnetic nickel-phosphorus underplating, while the body and coupling nut are stainless steel with a passivated finish. The insulator is PS, and a silicone rubber gasket enhances environmental sealing. Mechanical integrity is guaranteed with ≥500 mating cycles, axial captivation ≥20 N, and coupling torque of 1.65 Nm. Operating temperature range is -55°C to +165°C.
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.
