7-16 male connector LF 7/8"-50 TOPSPIN


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 TOPSPIN connectors for reliable and maintenance-free connections

A 7-16 male connector LF 7/8"-50 TOPSPIN transmits signals reliably for decades and without additional maintenance. SPINNER TOPSPIN connectors achieve an excellent sealing by an O-ring and an additional sealing sleeve to prevent the ingress of moisture or dust.

A 7-16 male connector LF 7/8"-50 TOPSPIN is ideally suited for installation on LF 7/8" annular corrugated copper LF cables.

The connector has a straight direction.

The 7-16 connector has become the most widely used coaxial connection system for mobile communication systems, due to its excellent mechanical and electrical properties. In order to achieve the industry leading intermodulation performance SPINNER applies silver-plating on all inner and outer conductor parts of the standard connector. As a supporting measure, we use exclusively non-magnetic materials, and we have minimized the number of RF contact points. The connection is especially suited for transmitting medium or high power indoors and outdoors.
