High-current connector for tight installation spaces on rail vehicles

HARTING has extended its Han HPR connector series with the addition of the Han 22 HPR slim: an ultra-slim high-current device optimised for up to four 250 A contacts

Equipped with a robust HPR housing made of die-cast aluminium, the connector is suited for use in high-power motor connections in the restricted spaces available in the underfloor areas of rail vehicles.

The connector was originally developed for a tram project in Vienna and by working in close co-operation with the customer, HARTING was able to fit the connector into the narrow gap of roughly 8cm between the carriage body and the bogie. Other housing dimensions were also optimised, with the result that the space requirement was reduced by some 40% compared to conventional solutions.

Manufacturers of rail vehicles are faced with increasing constraints on available space to house a rising number of electrical components. An ultra-slim solution such as the Han 22 HPR slim, with its significantly reduced dimensions, will help to meet the need for solutions that are able to offer compact dimensions with no impact on performance.
