The N Male RF connector, also termed the plug, is distinguished by its central pin and an outer shell that features a hexagonal or knurled design. This is complemented by a threaded coupling mechanism, which ensures a firm connection when mated with its counterpart, the N Female connector.

At the centre of the connector is a large pin, manufactured from conductive materials like gold-plated brass or silver-plated beryllium copper, this pin facilitates a dependable electrical connection. The design and dimensions of the pin are critical for obtaining an accurate fit with the female receptacle and for reducing signal losses during transmission.

The outer shell of the N Male connector serves two primary functions. Mechanically, it offers a strong connection, with the threaded coupling providing stability, especially in environments where vibration or movement might occur. From an electrical perspective, the shell delivers grounding and shielding, essential for minimising the risk of interference and ensuring the integrity of the RF signal.

The N Male's threaded coupling (not shown in the 3D rendering above) is a key feature, guaranteeing a secure connection when aligned and engaged correctly with the N Female connector. It's important to mate these connectors with care to maintain their functionality and avoid potential issues, such as cross-threading, particularly on N Female bulkhead connectors which often have a 'D' shaped chamfer to prevent twisting.
