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®) connectors with very effective protection against moisture and soiling

Attach a 4.3-10 male push-pull connector SF 1/4"-50 CAF® quick and easy in a single step. It provides very effective protection against moisture and soiling. It typically takes less than two minutes to install it since the connector is supplied as a single piece and only needs to be attached to the appropriately prepared cable end. For best results securely screw the SPINNER CAF® connector onto the prepared cable end along with its specially shaped profile gasket. This ensures an excellent seal thanks to the precisely fitting shape between the profile seal and the outer conductor. 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 male push-pull connector SF 1/4"-50 CAF® is also suitable for a variety of demanding applications in industry or broadcast (DVB, DAB, FM), SatCom or Radar.

A 4.3-10 male push-pull connector SF 1/4"-50 CAF® is ideally suited for installation on SF 1/4" 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.

The push-pull connection is quick and easy to loosen and yet provides enough grip and a secure fit. In addition, the center slots in the contacts provide high contact pressure between the cable and the connector for optimum conductivity and signal strength.
