CAN-BUS wire for high-temperature applications
Hradil, the specialist for non-standard-wires and special cables, has developed a high-temperature resistant CAN-Bus-wire which outer diameter measures less than 4,6 mm. The wire is adapted for minimal bending radiuses and is specially designed for the engine management environment.
The new Hradil CAN-Bus wire is primarily suitable as an engine management control cable and combines four properties: it is extremely thin, resists both high temperature as well as diesel fuel and oils and has a Bus-termination (termination impedance) of approximately 120 Ohm (like standard CAN-buses). It even allows bending radiuses of 30 mm or more by fixed installation.

In order to achieve an extremely small outer diameter, Hradil engineers have chosen to use Teflon which additionally enables this CAN-BUS wire to resist oils and fuels as well as cooling liquid, lubricants and soaps. It was also conceived to resist ozone and UV-radiation. Its working temperature ranges from -60°C to +150°C (by 3.000 hours long-term stress) or from -60°C to +200°C (by 300 hours long-term stress).
Alfred Hradil points out the widened field of application of this new CAN-Bus wire: “We designed this CAN-Bus for the extreme tough industry environment but also for its operation outdoor. This opens up completely new fields of applications for CAN-Bus wires.”

CAN-Bus background
In a CAN-Bus, all components are connected to a common data line (BUS) through single feeders. This way, the wiring work is reduced to a minimum and further applications can be quickly connected to the BUS. An access method (protocol) is necessary to control the data-flow of all individual components to the mutual BUS data line. The Controller Area Network (CAN) connects applications (nodes) together via a doubled-wire Bus-line. The Bosch company developed CAN-protocols in 1983 for the automotive industry. In a so-called open bus-system, components from different manufacturers can work together. Due to its high electromagnetic compatibility, its low costs and its real-time capability, the CAN-Bus technology is primarily applied in the automation engineering.
