Our history

To illustrate our company’s history, we’ve created a timeline for you. It covers all of the key events that have taken place over the course of SPINNER’s history, from the latest developments all the way back to the company’s establishment in 1946. Let’s get started:

A Leap Back to the Year 1946


SPINNER celebrats its 75th anniversary

In 2021, SPINNER looks back on 75 years of company history. Needless to say, a great deal has happened since 1946. We’ve evolved from a “one-man garage business” into a sprawling international enterprise with about 1000 employees worldwide and branches and dealerships in more than 40 countries.


SPINNER rotary joints fly to Mars

On board the Chinese Tianwen-1 Mars mission are special space-appropriate single- and dual-channel X-band rotary joints from SPINNER. This spacecraft is launched on July 23, 2020, becoming the first Chinese probe to go into orbit around the red planet on February 10, 2021.


5G – SPINNER is part of it!

SPINNER has already developed and marketed a large number of broadband distributed antenna system (DAS) components for gapless coverage of the frequency range from 380 MHz to 3,800 MHz.


Airspace surveillance becomes even safer

SPINNER has launched a completely new generation of ATC rotary joints to monitor air traffic across the board and in absolute safety.

A new connector housing bundles the entire range of connection types

Mobile communications are spawning new transmission technologies while antennas and base stations shrink. We respond to these requirements with an ingenious idea: a cluster connector that embraces the entire range of connection types, from coaxial across DC to AISG and fiber optics.


Active system for early detection of faults in antenna systems

The SPINNER Antenna Monitoring System (AMS) helps protect broadcast transmission systems from major damage by providing early warning of potential problems in the infrastructure.


The first contactless rotary joints that transmit data and power for Industry 4.0 applications

As a result of extensive networking of machines and systems, enormous data volumes are being generated in industry – also in rotating applications. Capacitive technology is used in mechanical and plant engineering, robotics, the food industry, packaging technology, medical technology and many other fields.


Everything made “easy”: revolutionary solutions for testing and measuring

The SPINNER EasySnake is a flexible dielectric waveguide that gives users unprecedented latitude for configuring test setups. The new EasyDocks and EasyLaunches also greatly help to simplify testing.


SPINNER expands into a new business segment by supplying rotary joints for industrial applications.

The company’s decades of experience with rotary joints for radars are now also applied to support data transmission in rapidly rotating production systems.


SPINNER rotary joints for Wi-Fi in aircraft

More and more planes are being equipped with Wi-Fi. The signals are transmitted by satellite communication systems, and SPINNER supplies the rotary joints needed to align the aircraft antennas.


4.3-10: SPINNER develops new connector system for the mobile communication market

In a consortium with three other leading connector suppliers, SPINNER has developed the new 4.3-10 connector system for the mobile communication market. It enables more compact systems with increasing performance requirements.

As part of the company’s international expansion, SPINNER opens its own sales office in USA to also provide the best possible service to customers in that country. Today, the company is based in Dulluth/Georgia.


SPINNER celebrates its 50th Anniversary

SPINNER hosts a celebration to thank all those who have remained with and supported the company until this anniversary, often for many decades. First and foremost, Mrs. Erika Spinner, who gave her husband all her support and encouragement to make his ideas a reality. Equally, all credit is given to the employees in Munich, Westerham and Lauenstein, who have often made the impossible possible. Their gratitude also goes out to all their customers, suppliers, and other business partners.
