HARTING for Transportation

HARTING connectors assist with weight reduction

Increased energy efficiency and weight reduction feature as major trends in the rail vehicle construction sector. But how do we improve rail vehicle energy efficiency?

Manufacturers of railway vehicles continuously try to reduce the energy consumption per passenger-kilometre driven. In addition to increasing capacity utilisation and using drives that are more efficient, weight is one of the most important levers in this respect.

Connectors can make a measurable contribution. By switching from metal to plastic in the interior of the vehicle, we have been able to reduce connector housing weight for trams and trains up to 50% between one generation and the next – this is the significant difference in weight between the Han® B aluminium die-cast and the Han-Eco® B plastic housing (for the same size).

The potential savings obviously seem low compared to the overall weight of a train, but manufacturers are scrutinising the design of their rail vehicles ever more closely – always looking for further opportunities to improve. Because the number of connectors used in trains rises, their proportion of the overall weight is also increasing.

Flat and compact: Han® 22 HPR Slim motor connector

HARTING has also continued developing its High Pressure Railway (HPR) housing range in recent years, making it possible to incorporate more connectors within a single housing. One of the biggest HPR housings, the Han® 34 HPR, will now take up to four 650 A high-current contacts or twelve individual Han-Modular® modules. In the past, it took two housings, each fitted with six individual Han-Modular® modules, to deliver comparable data supply.

Another HARTING solution that can help with weight reduction in the rail sector is the Han® 22 HPR Slim motor connector – its flat, compact shape making it particularly suited for use in underfloor areas. Miniaturisation has made room for four contacts in the connector – without compromising performance.

What our customers say:

Thanks to its easy assembly handling, the lightweight Han-Eco® product family saves us installation time. Furthermore, it simplifies the connectivity of our systems. We can design individual and compact solutions by choosing from a wide range of data, signal and power modules. Thanks to the Han-Eco® connectors, locomotives are more reliable and have lower maintenance and service costs.
