Acquisition of the Schleicher company expands Wieland's product range. Especially in the area of fieldbus, Ethernet, PC-based control and relay technology, the company benefits from the takeover. At that same time, Wieland launched a new product for outdoor areas. The RST® CLASSIC is a round connector for use in difficult environmental conditions. Since that time, the round plug is used for wiring outside lighting, construction site containers or solar systems. Thus, plug connectors systems from Wieland are also used in these areas.
A company is only as good as its employees. Whereas Wieland began production with 10 workers, by 1973 the company already employed 1000 people. The company continued to hire not only employees in administration but above all factory workers. At that time, production was focused on the first standardized connector for heating systems. As a result, the first pre-assembled electrical components for heating equipment appeared on the market under the name of "ST18".
In 1977, Wieland presented an innovation in the installation technology market. With the invention of the gesis® product group, cable connections can be plugged. The plug system saves over half the installation time. With gesis®, Wieland introduced the first safe electrical plug connection. The invention has proven itself to this day, enabling Wieland to gain market leadership in the area of pluggable electrical installation.
Since production of the Wieland terminal, Wieland developed into one of the leading companies in the market for electromechanical components. Soon, the products were already in high demand from abroad. Thus, Wieland began exporting. From the year 1970, products were sold to 51 countries on 5 continents. Over the course of time, Wieland established 14 subsidiaries all over the world.
In addition to productivity and efficiency of machines, functional safety is at the core of our efforts. According to the motto safety and safety service, Wieland developed various safety systems and safety control systems, guaranteeing the safe handling of machines. With safety analyses, Wieland provides support in the selection and implementation of required protective measures.
With the invention of a separable slotted terminal, Fritz Wieland propelled his company to success. Above all, the so-called Wieland terminal proved to be of higher quality than all other slotted terminals at that time. As the first safe electrical connection, the terminal proved itself millions of times over and was ultimately approved as a German imperial patent.
In the year 2015, Wieland's corporate mission was modernized. Since then, innovation and quality have been the driving forces for production and our interaction with employees and customers. The company is dedicated to responsible conduct in the areas of diversity, sustainability and social issues. Thus, Wieland is placing its focus on a green future.
Industry is undergoing a revolution – and Wieland is at the forefront. On the path towards intelligent production, Wieland is developing flexible installation concepts and communication solutions. The aim is to create the ideal infrastructure for industry and the building of the future; fully aligned with the company's motto: easy, quick + safe.
The development towards a solution provider opened up new opportunities for Wieland. Product systems were specified and combined through specialization on the fields of mechanical engineering, wind power, building and lighting technology, elevator systems and HVAC. This allowed the company to create an individual and flexible range.
In the aftermath of the fall of the Berlin Wall, Wieland expanded its sales activities from 1989. Through the establishment of several subsidiaries in Europe and overseas, initial branch locations were created in the United States, Canada and the United Kingdom. 11 additional subsidiaries followed in Europe and Asia.
