data directly to the driver’s monitor via the M12 Ethernet
connectors from HARTING.
In order to be able to monitor the entire passenger
compartment, the vehicle is equipped with eight cameras. In
addition, a single camera is mounted in each of the driver’s
cabs for track monitoring. The images from these cameras
are recorded and serve as documentation in the event of an
accident or any other critical traffic situation. This represents
a major improvement in terms of passenger safety.
HARTING connection technology
HARTING products are used across the board on the new
trams in Innsbruck. One central aspect here is their
use in Ethernet applications. Communications between
the multimedia computer and monitoring screens are
managed by a HARTING eCon 4080-B1 Ethernet Switch. The
information is transmitted across special Ethernet cables,
which are mostly routed in the roof of the vehicle. HARTING
M12 circular plug-in connectors are used as the connectors,
along with the HARTING IP 20 RJ45 Ethernet connectors with
quick connection technology. The M12 connectors have been
specially developed for demanding rail applications and
have D-coding and crimp contacts. At the modular vehicle
connection points, Quintax Z-contact connectors from the
Han® Modular System are used in Han® HPR (High Pressure
Railway) IP 68 housings for Ethernet data transmissions – a
successful combination which has proved itself in the field
for many years.
In the next generation, the power supply to the IP cameras
will be realized with the aid of the PoE (Power over Ethernet)
capable HARTING switch eCon 4080-BPOE. Here, the camera
is supplied with the required power from the Ethernet data
signal, which means that no additional cables need to be
installed for the power supply.
power supplies for cameras. Besides simple and time-saving
installation of components the new cabling layout also offers
significant weight savings thanks to the reduced number
of connectors and cables which are required, thus offering
improved energy efficiency and reduced impact on the
environment.
However, HARTING products are also deployed outside
Ethernet applications. For example, the industrial connectors
in the Han® (HARTING standard) series form the backbone
of the vehicle cabling. These connectors are equipped
with the necessary modules and used at the modular
vehicle connection points and also as device connectors for
subsystem components of the vehicle’s onboard equipment.
Thanks to the high quality plug connectors from HARTING,
SYCUBE can provide both the passenger information system
and the video monitoring system. Both of these systems
have been integrated in a single system. Dipl.-Ing. Gerhard
Kirschenhofer – CEO of SYCUBE Information Technology in
Vienna – was keen to play it safe in terms of the connectors:
“In every area, top quality components have been opted
for. Therefore, for us, it was absolutely essential to select
connectors of the highest quality”. SYCUBE makes it
possible: while the trams are on their way, passengers are
always kept up to date with top quality information.

Due to the fact that an Ethernet bus system that runs across
the vehicle is applied, the required amount of cabling can
be significantly reduced in comparison to the previous
point-to-point cabling with coaxial cables and separate
