1.85mm Jack (Female) Straight Field Replaceable Connector 4 Hole Flange, 8.6mm (.338 inch) DC-67GHz VSWR1.25

1.85mm Field Replaceable | Screw-lock | Stainless Steel Body

The ROSNOL V2BF50-0012A/9X connector is a high-frequency field-replaceable solution designed for precision 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.

Engineered for durability, the center contact is made of beryllium copper with gold plating over non-magnetic nickel-phosphorus underplating, while the body is stainless steel with a passivated finish. The insulator is PS, providing excellent dielectric properties. 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, with compliance to IEC 61169-1 standards for thermal shock, vibration, corrosion, and moisture resistance.

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.
