Reliable and efficient data communication for the Industry 4.0

TERZ Industrial Electronics interconnects all applications efficiently and reliably in the industrial automation. As a manufacturer, we take care of the design, development, manufacturing and distribution of industrial proofed Ethernet-based network components and industrial proofed data storage technologies, which operate reliably and safely even under the most adverse environmental conditions. Our product range includes highly optimized and powerful Industrial Ethernet switches, which enable operational safety even under the harshest electromagnetic, climatic and mechanical conditions. Designed and developed for use in factory automation & robotics and for operation in rail & road vehicles, cross-market key technologies of industry 4.0, Mobility 4.0 and the Industrial Internet of Things (IIoT) are bundled into robust and flexible products.


With Industrial Ethernet, the Ethernet standard is used for the connection of devices in industrial production plants. Wherever conventional bus systems reach their limits, for example due to insufficient bandwidth or networking capabilities, Industrial Ethernet-based infrastructures are increasingly used. Industrial Ethernet switches are an integral part of every modern communication link, thanks to their flexibility and performance. Due to the growth of seamless digitalization of production processes, a reliable communication based on a worldwide uniform standard is essential. In the future, Industrial Ethernet will also be used as a vital communication system in vehicle technology.

Industrial image processing is an essential component of the industry 4.0. Power over Ethernet allows the simultaneous transmission of data and energy via the twisted pair cable. This technology enables a seamless integration of image processing systems into industrial production systems in a flexible and cost-optimized manner. This also applies to the modernization and expansion of existing machines and industrial systems. The growing number of sensors and camera systems effectively extends the digital factory model supported by PoE.

In industrial applications, interference factors affect the network and its components, which have a significant impact on reliability, transmission quality and integrity. The risk of disturbances caused by vibrations, dirt, humidity and external electromagnetic influences is particularly high at the terminals, where connectors and devices are interconnected. Robust and resistant housings, outstanding EMC performance, low emitted interference and high interference immunity characterize our products.

Due to the increasing digitalization of the industry, the real and the virtual world are growing together into the Industrial Internet of Things. The decentralization of the installed communication devices and the increasing information transparency through IioT-sensors in the production facilities, are required to gain the needed flexibility. By increasing the efficiency and optimizing the infrastructure, downtimes and production losses can be avoided. Our products meet these challenges and offer reliability and planning security for the industry 4.0.

The integration of cross-market technologies offers innovative solutions for future requirements of the industry.
