Description
2.92mm Snap-On Plug (Male) to 2.92mm Jack (Female) | Straight Design | Snap-Lock & Screw-Lock | Stainless Steel Body
The ROSNOL AD-KQ1K25B/99X-9X is a precision RF adapter operating from DC to 40 GHz with 50 ohm impedance. It achieves a VSWR of ≤1.15 and insertion loss of ≤0.05 × √F GHz, ensuring excellent return loss performance. Electrical specifications include insulation resistance ≥5 GΩ, test voltage 750 Vrms, working voltage 250 Vrms, and RF leakage ≥100 dB up to 1 GHz. Snap-lock coupling on one side and screw-lock on the other provide secure engagement, with recommended torque of 0.80 to 1.10 Nm. Mechanical durability is rated at ≥500 mating cycles.Engineered with premium materials, both sides use beryllium copper center contacts with gold plating over nickel-phosphorus underplating, stainless steel bodies and coupling nuts passivated, and PEI insulators for dielectric stability. The adapter operates reliably from −55°C to +165°C.
ROSNOL’s RF adapters deliver precision, consistency, and value, making them a competitive alternative to major European and American brands. All products are manufactured under ISO 9001 certified processes and comply fully with RoHS and REACH. Customization for materials, plating, and mechanical design is available to support specialized interconnect needs.
