Robust communications interface for rail & harsh industrial applications!

Han® Coax ETCS connector, from Harting, features robust communications interface for rail and harsh industrial applications

The Han® Coax ETCS connector is a high-performance coaxial connector designed to provide a reliable and robust interface for data transmission in railway applications and in harsh industrial environments.

The connector was originally developed for use in the European Train Control System (ETCS), in which the signal communication between the rail vehicle and the track bed is controlled by a system known as the "Eurobalise". Since this is a safety-related system, components are required that operate with high reliability over the entire product life.

Special Eurobalise coaxial cables are used on board the trains and in stationary facilities, which in turn have to be equipped with appropriate interfaces at various positions. Thanks to the Han® Coax ETCS connectors, these positions can now be equipped with a very reliable and robust interface.

A key feature of the connector is the crimp flange, which incorporates an additional crimp barrel to secure the screening braid permanently with high mechanical and electrical integrity, while at the same time providing strain relief for the cable.

The connector incorporates a screened coaxial Han-E® crimp contact with an impedance of 50 ohms, and is optimised for large conductor diameters up to 12 mm.

The Han® Coax can be fitted compactly into the established Han® 3A and Han® 3 HPR housing - making it ideally suited for robust coaxial data interfaces.
