The ZG05HV Series WTB connector supports applications up to 125 degree C, making it suitable 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 and 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.

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.
