Hirose Electric ZE150HV High-Voltage Wire-to-Board Connectors

Introduction

Hirose Electric ZE150HV connectors are compact high-voltage wire-to-board interconnects developed for demanding electrified-vehicle power systems. Designed to combine reliable electrical performance with space-efficient packaging, these connectors support high-voltage connections in EV and HEV equipment.

Part Description

The ZE150HV series is a high-voltage wire-to-board connector family rated for applications up to 1000V AC/DC and currents up to 10A per pin. Its 4.5mm pitch supports compact board-level layouts while maintaining the insulation distances needed for high-voltage systems.

Rib technology is incorporated into the connector design to optimize creepage and clearance distances. This helps support insulation reliability in compact equipment exposed to high electrical potential differences.

The connector uses dual-spring, three-point contacts to provide stable contact engagement and dependable electrical continuity. A connector position assurance mechanism further improves connection security by helping ensure that mating is complete and retained during operation.

ZE150HV connectors are specified for operating temperatures up to +125°C, making them suitable for automotive locations where elevated ambient temperatures, vibration, and long-term reliability are important considerations.
