Datasheet

HARTING has designed a new Han 34 HPR EasyCon connector for high-current transmission with a high power density, making it suited to use in rail vehicles. Han 34 HPR housings and retaining frames are designed in such a way that, for the first time ever, a connector is now available that can accommodate four 650 A contacts alongside one another in a single interface.

This more than doubles the connector’s current-carrying capacity compared to the next HPR connector size down, saving space for the end-user. However, the housing dimensions have not increased to the same degree: the housing width is only a third more than the smaller alternative.

The new connector is available in an angled version for inter-car car transitions and a straight version for connections to traction units.

The housing also allows 12 individual Han-Modular modules to be inserted as an alternative to the 650A high-current contacts. Until now, two housings equipped with six Han-Modular individual modules each had to be used to obtain a comparable power supply.

The Han-Modular series offers over 100 different inserts for the transmission of power, signals and data, enabling a wide range of combination options. Intelligent modules in the smart Han range complete the offering, including an ID module which gives rail components an identity that can be called up on networks. In addition, networks can be extended by integrating the new 4-port Ethernet switch US4, which uses minimum space.
