4.3-10 male screw connector LF 1/2"-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 4.3-10 male screw connector LF 1/2"-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 6.0 GHz for in-building Distributed Antenna Systems (DAS) or on mobile communication base stations outdoors. In addition, a 4.3-10 male screw connector LF 1/2"-50 CAF® Plast2000 is also suitable for a variety of demanding applications in industry or broadcast (DVB, DAB, FM), SatCom or Radar.

A 4.3-10 male screw connector LF 1/2"-50 CAF® Plast2000 is ideally suited for installation on LF 1/2" annular corrugated copper LF 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.

The screw connection, especially when mounted with a suitable torque wrench, provides the strongest hold and a constantly secure fit of the cable. In addition, the center slots in the contacts provide high contact pressure between the cable and the connector for optimum conductivity and signal strength.
