4.3-10 female connector SF 1/2"-50 Spinner MultiFit®


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 MultiFit® connectors for quick and secure installations

A 4.3-10 female connector SF 1/2"-50 Spinner MultiFit® is one of the most versatile connectors of our portfolio. It transmits signals maintenance-free and reliably for decades without additional effort. A quick and secure two-step installation can be done in about two minutes. Sealing is accomplished by a specially shaped profile gasket that is screwed onto the outer conductor first. Then the back-nut is screwed onto the profile gasket. This provides an excellent seal to prevent the ingress of moisture or dust. Thus we guarantee an outstanding lossless mobile communication quality in a frequency range from DC to 6 GHz for in-building Distributed Antenna Systems (DAS) or on mobile communication base stations outdoors. In addition, a 4.3-10 female connector SF 1/2"-50 Spinner MultiFit® is also suitable for a variety of demanding applications in industry or broadcast (DVB, DAB, FM), SatCom or Radar.

A 4.3-10 female connector SF 1/2"-50 Spinner MultiFit® is ideally suited for installation on SF 1/2" helical corrugated copper SF cables.

The connector has a straight direction.

The 4.3-10 connector system was designed to meet the latest requirements in mobile communication in terms of size, robustness, performance, and other parameters. Its small footprint supports the use of smaller components, mitigates risks if equipment is assembled without due care, and delivers outstanding electrical performance.
