High-voltage wire-to-board connector from Hirose

The ZG05HV Series WTB connector supports applications up to 125C, making it ideal for automotive applications including battery, converter, ECU, inverter and on-board charging connectivity. The ZG05HV Series connector is also commonly used in storage battery applications.

The ZG05HV Series features a specialised housing that delivers sufficient creepage and spatial distance between contacts, enabling a high-rated voltage (1,000V) and withstanding voltage (3,000V) in a compact size. With a pitch of 3.3 mm, the size 0.5mm tab-sized connector combines space-savings and high performance without compromising reliability.

A 3-point contact design (one spring and two embossed contact points) combined with a double-layered spring increases the contact force and prevents vibration from outside, enhancing reliability in high-vibration conditions. In addition, the depth of the contacts within the housing eliminates the risk of electric shock during assembly.

“The ZG05HV Series is designed for high-voltage applications that experience extreme vibration,” said Pete Lais, Assistant Vice President of Product Management for Hirose Electric Americas. “The new wire-to-board connector meets customer demand for a high-heat and -vibration-resistant connector that supports high-voltage applications – all in a smaller form factor.”

A mating key prevents mis-mating when using multiple connectors.

The ZG05HV Series is currently available in a 6-position version, with a 10-position connector under development.
