Bus cables for industrial and building automation
Bus cables are a core component in modern industrial automation and digital communication systems. They enable fast, stable data transmission between sensors, actuators, controllers, and electronic devices in machinery and production lines, meeting increasingly high demands for speed, accuracy, and operational efficiency.
By transmitting control signals from the central controller to the entire bus network - where only specifically addressed devices respond - the bus system optimizes cable infrastructure, reduces installation costs, and enhances operational reliability. As a result, bus cables are likened to the nervous system of modern technology and automation systems.
HELUKABEL offers a comprehensive range of bus cables and conductors for all common bus systems, effectively meeting the needs of industrial automation, building technology, and advanced digital communication infrastructure.
- Profibus cables are widely used due to their ability to operate reliably in harsh environments.
- In the automotive manufacturing industry, bus cables ensure precise coordination between robots and sensors even when subjected to strong electromagnetic interference.
- KNX bus cables enable effective control of lighting, air conditioning, and security systems in smart buildings.
- In the field of logistics and warehousing, fieldbus cables are a key solution for conveyor systems and automated warehouse management.

DeviceNet bus cables
The special aspect of this bus system is that a data pair and a power supply pair are always integrated in one cable. The small cross-section is used for short distances
or as a point-to- point connection; the large cross-section as main conductor for long distances and frequently in combination with the thin conductor as drain wire.

AS-Interface cables
With the AS interface, the cable assembly from the control system to the sensor/actuator
is not needed. The AS interface is the field bus system that transmitts both data and power in one single cable. With fast contacting in penetration technique, the possibility of errors in cabling is largely reduced. The special outer jacket provides protection against oil, grease, and refrigerant lubricants, and the cable is therefore even suitable for applications in wet surroundings, in machinery and plant construction, as well as in the machine tool and automotive industry

Bus cables for building automation EIB / E-BUS / KNX / Hospital bus
Bus cables are used in building automation and technology to create a modern building infrastructure that is smarter, more efficient, and convenient. They enable comprehensive networking and control of various systems.
EIB bus cables laid the groundwork for building automation. The European Installation Bus System was established as the standard for intelligent buildings. KNX cables are a newer development that combines EIB, BatiBUS, and EHS into a unified standard. Both systems use the same cabling but differ in their protocol variety. KNX offers more flexibility with device integration and is compatible with EIB.
