N Jack (Female) Straight Connector 4 Hole Flange, 12.7mm (.500 inch) DC-11GHz VSWR1.20

N Jack (Female) | Solder Attachment | 4 Hole Flange | Brass Body

The ROSNOL N2GFA50-2720A/H4 is an N Jack (Female) connector engineered for panel-mounted RF interfaces requiring stable broadband performance from DC to 11 GHz. Designed with a 50 Ω impedance, VSWR ≤ 1.20, and low insertion loss, it ensures consistent signal integrity across high‑frequency communication and instrumentation systems. Mechanical specifications include a screw‑lock coupling mechanism, ≥ 500 mating cycles, a soldered stub‑type center terminal with mechanical captivation, and a recommended torque range of 0.7–1.1 Nm. The 4‑hole flange incorporates a 12.7 mm (0.500 inch) hole spacing pattern, enabling secure mounting to enclosures, bulkheads, or RF cavity structures.

Piece parts and plating are optimized for durability and RF stability: the centre contact is phosphor bronze with gold plating over a non‑magnetic nickel‑phosphorus underplate; the body is fabricated from a brass copper–tin–zinc alloy; the insulator is PTFE; and the gasket is high‑reliability silicone rubber. As a panel‑mount interface, this connector mates with standard 50 Ω N‑type plug connectors used in laboratory measurement setups, communication racks, and industrial microwave systems. This design makes it suitable for equipment I/O transitions, test ports, and RF subsystem integration where stable N‑type panel connectivity is required.

ROSNOL’s RF components offer high performance at competitive pricing, providing dependable alternatives to leading European and American brands. All ROSNOL products are manufactured in ISO 9001‑certified facilities and fully comply with RoHS and REACH regulations. Customization services for materials, plating, and mechanical configuration are available to support specialized RF and microwave system requirements.
