Rosenberger has expanded its portfolio of high-voltage connectors with the launch of the new HVR®25 series. The HVR®25 is the smallest shielded high-voltage connector compared to latest class 2 connectors. It offers a current capacity of up to 40 A with a cable cross section of 4 mm². With its compact design, high reliability, and optimized cost-performance ratio, the HVR®25 is fully in line with Rosenberger’s principle of "Precision Without Complexity."
As vehicle architectures evolve toward 800- and 1,000-volt system platforms, precise and efficient connector solutions have never been more important. The HVR®25 was specifically developed for low-current auxiliary systems that require efficiency, safety, and ease of integration. Typical applications include PTC heaters, inverters, and onboard chargers (OBCs).
Compact, smart, and efficient
Compared to current Class 2 connectors, the HVR®25 reduces space and weight by up to 50%, as well as significantly reducing the cost of both, the connector and the cable assembly. Its compact design simplifies packaging and strikes an optimal balance between performance, size, and cost efficiency.
Reliable and safe performance
The HVR®25 meets standards of vibration according to LV215-2 & SG3 and USCAR. It is RoHS compliant and features shielding and an integrated HVIL (high voltage interlock). The system achieves protection classes of up to IP6K9K when mated and IPXXB when unmated. Its operating temperature range of –40 °C to +125 °C ensures reliable performance under harsh environmental conditions.
Flexible product portfolio
The product family includes cable connectors and headers with a common interface for cable cross sections ranging from 1.5 mm² to 4 mm².
Rosenberger's HVR®25 is a solution that aligns with the technical requirements of modern 800 V and 1000 V architectures, reducing system complexity, weight, and cost. These features establish the HVR®25 as a new benchmark in high-voltage connector technology.
"The HVR®25 embodies our principle of 'Precision Without Complexity,' offering uncompromising performance in a compact design," says Günther Höfelmeier, Director of Product Management at Rosenberger.
