N male connector LF 7/8"-50 CAF® Plast2000


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.

SPINNER Cut and Fit (CAF®) Plast 2000 connectors for extremely harsh environmental conditions

A N male connector LF 7/8"-50 CAF® Plast2000 is available for LF cables with annular corrugated copper outer conductor and is especially well-suited for extremely harsh environmental conditions, e.g. high humidity, ice or contamination. The cable clamp is completely filled by injecting SPINNER Plast2000 sealing compound to rule out any chance of moisture, sand etc. penetrating into the connector. This prevents internal corrosion and ensures superb electrical and mechanical performance for decades. Thus we guarantee an outstanding lossless mobile communication quality in a frequency range from DC to 3.8 GHz for in-building Distributed Antenna Systems (DAS) or on mobile communication base stations outdoors. In addition, a N male connector LF 7/8"-50 CAF® Plast2000 is also suitable for a variety of demanding applications in industry or broadcast (DVB, DAB, FM), SatCom or Radar.

A N male connector LF 7/8"-50 CAF® Plast2000 is ideally suited for installation on LF 7/8" annular corrugated copper LF cables.

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.
