2.92mm Jack (Female) Straight Field Replaceable Connector 2 Hole Flange, 12.22mm (.481 inch) DC-40 GHz VSWR1.25

2.92mm Field Replaceable | Screw-lock | Stainless Steel Body

The ROSNOL HS‑K2BT50‑0012A/9X is a 2.92mm Jack (Female) field‑replaceable connector designed for 2‑hole flange mounting with a 12.22 mm [.481 in] hole spacing and an integrated hermetic seal 0.012 inch. Engineered for stable RF performance from DC to 40 GHz, the connector features 50‑ohm impedance, ≤1.25 VSWR, high insulation resistance, and a 750 V rms test voltage rating, ensuring reliable low‑loss transmission for precision high‑frequency applications. The screw‑lock interface supports at least 500 mating cycles, while a captivated center contact provides ≥20 N retention force for mechanical stability.

The connector uses a beryllium copper center contact with gold plating over a non‑magnetic nickel‑phosphorus underplating for excellent conductivity and corrosion resistance. Its passivated stainless‑steel body provides strong structural durability, while hermetic seal components—including a Kovar center contact and body with Corning 7070 glass—ensure superior sealing performance in demanding environments. A PEI insulator maintains stable dielectric characteristics across wide temperature ranges. These material characteristics make the HS‑K2BT50‑0012A/9X suitable for microwave modules, precision test systems, and field‑replaceable interfaces requiring hermetic sealing.

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.
