Description
N Jack (Female) | Soldered or Crimped Cable Entry | Screw-lock | Brass Body
The ROSNOL N2KA50-0250A/H4 is a bulkhead-mount N Jack (Female) connector designed for 50 Ω RF systems operating up to 11 GHz. Featuring a screw-lock coupling mechanism and a soldered or crimped cable entry with solder clamp structure, this connector ensures secure mechanical retention and stable signal transmission. It offers a VSWR of ≤1.15 (≥23.1 dB), insertion loss ≤0.05 dB, and supports working voltages up to 1400 V rms, making it suitable for high-power RF applications.The connector body is made of brass with Copper-Tin-Zinc alloy plating. The center contact is phosphor bronze with gold plating over nickel underplating, and the insulator is PTFE. The gasket is silicone rubber, and fastening components such as the nut and washer are also brass with Copper-Tin-Zinc alloy plating. Compatible cable types include SR-250, SF-250, RSF 250 FEP, RSF 250 PVC, RG401, and Belden 1675A.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment.
