N female connector RA12-50 radiating cable 1/2"-50


SPINNER Connectors - Low-Loss And Reliable Connection For Highest Requirements

Connectors for the transmission of high-frequency signals are used in a wide variety of industries such as mobile communication, broadcast, measurement, satellite communication or in radar technology. SPINNER connectors ensure optimal, low-loss signal transmission and extremely sustainable, cost-effective connections. SPINNER connectors are robust and resistant in various climatic environments - from the sea to the desert or even space.

They guarantee excellent electrical and mechanical performance values such as stability for enduring connectivity, meeting the highest sealing requirements and high performance for transmission parameters.

In the case of an N female connector RA12-50 radiating cable 1/2"-50, the trimmed cable is inserted into the connector. The shrink tube that has been pushed on is then shrunk using a hot air blower or a soft flame until a weatherproof seal and a durable connection is achieved.

A N female connector RA12-50 radiating cable 1/2"-50 is ideally suited for installation on radiating cables. The premium design with flared internal and external contacts ensures maximum reliability with high RF power. All connectors have sealed flanges and inlets for overpressure operation.

The connector has a straight direction.

The N-coaxial connectors were named after their inventor Paul Neill, who developed this standard for RF connectors in 1942. Often, however, the name also relates to the Navy Connector. Type N connectors can be used at frequencies up to 11 GHz, high-precision types up to 18 GHz. It is typically used in mobile communication applications with demanding mechanical and electrical requirements. SPINNER exclusively manufactures connectors with non-slotted outer conductor contacts and a special sealing profile in the connector head instead of the flat seal disk, specified by IEC or CECC. This ensures the most reliable sealing function.
