Hirose has announced the commercial availability of its ZE150HV Series wire-to-board connector for electric vehicle (EV) and hybrid electric vehicle (HEV) powertrains.
The connector uses a 4.5-mm pitch and is rated for up to 1,000 V ac/dc and 10 A per pin. It operates at temperatures up to 125° C.
The ZE150HV Series is designed to IEC 60664 requirements for Pollution Degree 2 environments and altitudes up to 6,000 m. Its heat-resistant materials are RoHS2 compliant.
For high-voltage EV systems, Hirose uses proprietary ribs between the contacts to reduce the spacing normally required between pins at 1,000 V. The design is intended to reduce connector size in compact powertrain assemblies.
The terminal uses a three-point contact structure with a double-spring design to maintain contact force under vibration. Hirose says this is intended for locations near EV motors and inverters where mechanical movement can affect connection stability.
A built-in connector position assurance (CPA) mechanism helps prevent incomplete mating, reducing the risk of improper electrical connection in high-voltage systems.
The ZE150HV Series was selected as a CES Innovation Awards 2026 Honoree in the Vehicle Tech & Advanced Mobility category and is now commercially available.
