Introducing IRISO’s “10128 Series” Narrow-Pitch Connector for Electric Vehicle Powertrains

On June 12, 2020 IRISO Electronics (CEO Ikuo Yuki, headquartered in Yokohama City, Kanagawa, Japan), announced an additional variation of the internal BtoB “Z-Move™” connector resonance absorption functioning “10128 Series”. Due to demand, the 10128 Series is now available with narrow picth-type and Z-Move™ capabilities that will meet a variety of customer needs.
The “10128 Series” internal BtoB connector, featuring a 0.8mm pitch with Z-Move™ functionality, was specifically developed for electric vehicle powertrains (EV/PHV/HV). IRISO’s unique “Z-Move™” floating technology, where the Z axis moves while the contacts are fixed, has been widely adopted for it’s durability in extreme vibrating and shock resistant environments.

Product Features

Feature 1: Narrow-Pitch / Miniaturization
An 0.8 mm pitch has been added the existing product series. The unique Z-Move™ technology allows the contact to follow resonance in the Z direction, absorbing substrate resonance which creates high contact reliability. This prevents the degredation of the contact due to minute sliding wear and tear. In addition, a simulation service is being made available, reflecting years of experience with past evaluation results. By partnering with customers during the initial design stage, we are able to propose more effective use of our connectors.
Feature 2: High Temperature Performance
A connector’s performance at higher temperatures is required due to the increase in heat generation around the engine and due to the increasing functionality of devices. Our high-temperature performance products can be used with confidence even in harsh high temperature environments.​
Feature 3: Two-Point Contact
Two-Point Contact provides reliable connections even in an environment where dust and dirt occur by reliably removing foreign matter at the front contact. It can be confidently be used in devices that require high connection reliability.
Feature 4: Robot Assembly Compatible Connectors
Robot assembly contributes to a higher level of quality, stabilization of production takt time and cost savings. Therefore, IRISO has developed the concept of a “Robot Assembly Compatible Connector” suitable for robot assembly. To reduce foreign matter adhesion, mounting and mating misalignment, and incomplete mating during assembly, our “Robot Assembly Compatible Connectors” have a “Floating” function that absorbs board misalignments and a “Two-Point Contact” function that removes foreign matter adherence.
